Some words may have different meanings when used in other contexts. There are variations in the use of periods and capitalization for abbrevia- tions, acronyms and standard measures. The terms in this glossary are pre- sented without periods. ABNORMAL COMBUSTION – Combustion in which knock, pre-ignition, run- on or surface ignition occurs; combustion that does not proceed in the nor- mal way (where the flame front is initiated by the spark and proceeds throughout the combustion chamber smoothly and without detonation). ABSOLUTE PRESSURE – Pressure shown on the pressure gauge plus at- mospheric pressure (psia). At sea level atmospheric pressure is 14.7 psia. Use absolute pressure in compressor calculations and when using the ideal gas law. See also psi and psig. ABSOLUTE TEMPERATURE – Temperature scale with absolute zero as the zero of the scale. In standard, the absolute temperature is the temperature in ºF plus 460, or in metric it is the temperature in ºC plus 273. Absolute zero is referred to as Rankine or r, and in metric as Kelvin or K. -
Thermodynamics Introduction and Basic Concepts
Thermodynamics Introduction and Basic Concepts by Asst. Prof. Channarong Asavatesanupap Mechanical Engineering Department Faculty of Engineering Thammasat University 2 What is Thermodynamics? Thermodynamics is the study that concerns with the ways energy is stored within a body and how energy transformations, which involve heat and work, may take place. Conservation of energy principle , one of the most fundamental laws of nature, simply states that “energy cannot be created or destroyed” but energy can change from one form to another during an energy interaction, i.e. the total amount of energy remains constant. 3 Thermodynamic systems or simply system, is defined as a quantity of matter or a region in space chosen for study. Surroundings are physical space outside the system boundary. Surroundings System Boundary Boundary is the surface that separates the system from its surroundings 4 Closed, Open, and Isolated Systems The systems can be classified into (1) Closed system consists of a fixed amount of mass and no mass may cross the system boundary. The closed system boundary may move. 5 (2) Open system (control volume) has mass as well as energy crossing the boundary, called a control surface. Examples: pumps, compressors, and water heaters. 6 (3) Isolated system is a general system of fixed mass where no heat or work may cross the boundaries. mass No energy No An isolated system is normally a collection of a main system and its surroundings that are exchanging mass and energy among themselves and no other system. 7 Properties of a system Any characteristic of a system is called a property. -

Insights Into the Unification of Forces
Insights into the unification of forces John A. Macken Previously unknown simple equations are presented which show a close relationship between the gravitational force and the electromagnetic force. For example, the gravitational force can be expressed as the square of the electromagnetic force for a fundamental set of conditions. These equations also imply that the wave properties of particles are an important component in the generation of these forces. These insights contradict previously held assumptions about gravity. In response to the question “Which of our basic physical assumptions are wrong?” this article proposes that the following are erroneous assumptions about gravity: 1 Gravity is not a true force. For example, the standard model does not include gravity and general relativity characterizes gravity as resulting from the geometry of spacetime. Therefore general relativity does not consider gravity to be a true force. 2 Gravity was united with the other forces at the start of the Big Bang but today gravity is completely decoupled from the other forces. For example, at the start of the Big Bang fundamental particles could have energy close to Planck energy and the gravitational force between two such particles was comparable to the electrostatic force. However, today the gravitational force is vastly weaker than the other forces and is assumed to be completely different than the other forces. 3 The forces are transferred by messenger particles. For example, the electromagnetic force is believed to be transferred by virtual photons and the gravitational force is believed by many physicists to be transferred by gravitons. Gravity has always been the most mysterious of the forces 1 ‐ 3. -
Fast, Computer Supported Experimental Determination of Absolute Zero Temperature at School
European J of Physics Education Volume 5 Issue 1 2013 Bogacz & Pedziwiatr Fast, Computer Supported Experimental Determination of Absolute Zero Temperature at School Bogdan F. Bogacz Antoni T. Pędziwiatr M. Smoluchowski Institute of Physics Department of Methodics of Teaching and Methodology of Physics Jagiellonian University Reymonta 4, 30-059 Cracow, Poland E-mail: [email protected] (Received: 14.11. 2013, Accepted: 31.12.2013) Abstract A simple and fast experimental method of determining absolute zero temperature is presented. Air gas thermometer coupled with pressure sensor and data acquisition system COACH is applied in a wide range of temperature. By constructing a pressure vs temperature plot for air under constant volume it is possible to obtain - by extrapolation to zero pressure - a reasonable value of absolute zero temperature. The proposed way of conducting experiment allows students to "discover" intuitively the existence of minimal possible temperature and thus to understand the reason for introducing the concept of absolute zero temperature and absolute temperature Kelvin scale. It is a convincing and straightforward method to enhance understanding the general concept of temperature and support teaching thermodynamics and heat - mainly at secondary schools. This experiment was used with our university students who are being prepared to teach physics in secondary schools. They prepared physics lesson based on this material and then discussed didactic value of this material both for pupils and for teachers. Keywords: Physics education, absolute temperature, absolute zero determination, air gas thermometer. Introduction Temperature is a thermodynamic concept characterizing the state of thermal equilibrium of a macroscopic system. Equality of temperatures is a necessary and sufficient condition for reaching thermal equilibrium. -
Norms and Facts in Measurement
CORE Metadata, citation and similar papers at core.ac.uk Provided by Lirias Fundamenta/ measurement concepts Norms and facts in measurement J. van Brakel Foundations of Physics, Physics Laboratory, State University of Utrecht, PO Box 80.000, 3508 TA Utrecht, The Netherlands Publications concerned with the foundations of measurement often accept uncritically the theory/observation and the norm/fact distinction. However, measurement is measurement-in-a-context. This is analysed in the first part of the paper. Important aspects of this context are: the purpose of the particular measurement; everything we know; everything we can do; and the empirical world. Dichotomies, such as definition versus empirica//aw, are by themselves not very useful because the 'rules of measure- ment' are facts or norms depending on the context chosen or considered. In the second part of the paper, three methodological premises for a theory of measurement are advocated: reduce arbitrariness, against fundamentalism, and do not be afraid of realism. The problem of dichotomies • Extensive quantities are additive (mass, velocity, utility) • The empirical relation > (for mass, length, temperature, In the literature on the foundations of measurement, a ...) is transitive (Schleichert, 1966; Carnap, 1926; number of dichotomies are used in describing properties of Janich et al, 1974) statements about various aspects of measurement.

Some other dichotomies that roughly correspond to the two just mentioned are These are examples of statements for which it is not given in Table 1. -

Measuring Temperature
PhyzGuide: Measuring Temperature THE THERMOSCOPE AND THE THERMOMETER Galileo is given credit for developing the first temperature-measuring device toward the end of the 1500s. Air in a tube with a bulb at the top is heated. The open end of the tube is immersed in water or wine. As the air in the tube cools, it contracts and is drawn into the tube. Once an equilibrium point is established, a rise in temperature increases the volume of the gas, forcing fluid back down; a fall in temperature reduces the volume of the gas, drawing more HOT COLD fluid into the tube. This device was Galileo’s thermoscope. Early in the 1700’s, Gabriel Daniel Fahrenheit developed a more reliable temperature measuring device. A thin glass tube holds a volume of mercury in a bulb at the bottom. When heated, the mercury expands upward in the tube. The tube could be sealed and allowed for accurate, reproducible temperature readings. Because this device could be reproduced and marked with a numerical scale, it was called a thermometer. FAHRENHEIT AND CELSIUS: UNRELATED RELATIVE SCALES As inventor of a reliable thermometer, Fahrenheit was afforded the luxury of developing a temperature scale to his liking. He defined a temperature scale on which 0 was the coldest temperature he could reproduce in the lab (the temperature of an ice-salt mixture) and 96 as human body temperature.The fact that 96 is divisible by 2, 3, and 4 made it easy to mark off increments on the glass tube between 0 and 96 once those endpoints were established. -
Lesson 2: Temperature
Lesson 2: Temperature Notes from Prof. Susskind video lectures publicly available on YouTube 1 Units of temperature and entropy Let’s spend a few minutes talking about units, in partic- ular the Boltzmann constant kB, a question about which last chapter ended with. What is the Boltzmann constant? Like many constants in physics, kB is a conversion factor. The speed of light is a conversion factor from distances to times. If something is going at the speed of light, and in a time t covers a distance x, then we have x = ct (1) And of course if we judiciously choose our units, we can set c = 1. Typically these constants are conversion factors from what we can call human units to units in some sense more fun- damental. Human units are convenient for scales and mag- nitudes of quantities which people can access reasonably easily. We haven’t talked about temperature yet, which is the sub- ject of this lesson. But let’s also say something about the units of temperature, and see where kB – which will simply be denoted k when there is no possible confusion – enters the picture. Units of temperature were invented by Fahren- heit1 and by Celsius2, in both cases based on physical phe- 1Daniel Gabriel Fahrenheit (1686 - 1736), Polish-born Dutch physicist and engineer. 2Anders Celsius (1701 - 1744), Swedish physicist and astronomer. 2 nomena that people could easily monitor. The units we use in physics laboratories nowadays are Kelvin3 units, which are Celsius or centrigrade degrees just shifted by an additive constant, so that the 0 °C of freezing water is 273:15 K and 0 K is absolute zero.
