Saturation • If we cap the air over the water, then more and more water molecules will enter the air until saturation is reached. • At saturation there is a balance between the number of water molecules leaving the liquid and entering it. • Saturation can occur over ice too. Hydrologic Cycle 2 Air Parcel • Enclose a volume of air in an imaginary thin elastic container, which we will call an air parcel. • It contains oxygen, nitrogen, water vapor, and other molecules in the air. 1. Absolute Humidity Mass of water vapor Absolute humidity = Volume of air The absolute humidity changes with the volume of the parcel, which can change with temperature or pressure. 2. Specific Humidity Mass of water vapor Specific humidity = Total mass of air The specific humidity does not change with parcel volume. 3 Specific Humidity vs. Latitude • The highest specific humidities are observed in the tropics and the lowest values in the polar regions.

It has been accepted for inclusion in Robert Katz Publications by an authorized administrator of DigitalCommons@University of Nebraska - Lincoln. 17 The Phases of Matter 17-1 Phases of a Substance A substance which has a definite chemical composition can exist in one or more phases, such as the vapor phase, the liquid phase, or the solid phase. When two or more such phases are in equilibrium at any given temperature and pressure, there are always surfaces of separation between the two phases. In the solid phase a pure substance generally exhibits a well-defined crystal structure in which the atoms or molecules of the substance are arranged in a repetitive lattice. Many substances are known to exist in several different solid phases at different conditions of temperature and pressure. These solid phases differ in their crystal structure. Thus ice is known to have six different solid phases, while sulphur has four different solid phases.

    Compressed Liquid Gases (Cryogens) Laboratory Safe Work Practices Source: Section 3.9 of Guidelines for Safe Work Practices in Human and Animal Medical Diagnostic Laboratories: Recommendations of a CDC-convened, Biosafety Blue Ribbon Panel; excerpted by Vanderbilt OCRS, 10.2020. Compressed Liquid Gases (Cryogens) Cryogenic liquids are liquefied gases that have a normal boiling point below -238°F (-150°C). Liquid nitrogen is used in the microbiology laboratory to freeze and preserve cells and virus stocks. The electron microscopy laboratory, frozen section suites, and grossing stations for surgical pathology frequently use liquid nitrogen; some laboratories also use liquid helium. The principal hazards associated with handling cryogenic fluids include cold contact burns and freezing, asphyxiation, explosion and material embrittlement. Cold contact burns and freezing • Liquid nitrogen is dangerously cold (-320°F [-196°C]), and • Wear loose-fitting thermal gloves with elbow-length cuffs skin contact with either the liquid or gas phase can when filling dewars.

  • Pressure Vs Temperature (Boiling Point)
    Boiling Points and Vapor Pressure Background Boiling Points and Vapor Pressure Background: Definitions Vapor Pressure: The equilibrium pressure of a vapor above its liquid; the pressure of the vapor resulting from the evaporation of a liquid above a sample of the liquid in a closed container. Boiling Point: The temperature at which the vapor pressure of a liquid is equal to the atmospheric (or applied) pressure. As the temperature of the liquid increases, the vapor pressure will increase, as seen below: https://www.chem.purdue.edu/gchelp/liquids/vpress.html Vapor pressure is interpreted in terms of molecules of liquid converting to the gaseous phase and escaping into the empty space above the liquid. In order for the molecules to escape, the intermolecular forces (Van der Waals, dipole- dipole, and hydrogen bonding) have to be overcome, which requires energy. This energy can come in the form of heat, aka increase in temperature. Due to this relationship between vapor pressure and temperature, the boiling point of a liquid decreases as the atmospheric pressure decreases since there is more room above the liquid for molecules to escape into at lower pressure. The graph below illustrates this relationship using common solvents and some terpenes: Pressure vs Temperature (boiling point) Ethanol Heptane Isopropyl Alcohol B-myrcene 290.0 B-caryophyllene d-Limonene Linalool Pulegone 270.0 250.0 1,8-cineole (eucalyptol) a-pinene a-terpineol terpineol-4-ol 230.0 p-cymene 210.0 190.0 170.0 150.0 130.0 110.0 90.0 Temperature (˚C) Temperature 70.0 50.0 30.0 10 20 30 40 50 60 70 80 90 100 200 300 400 500 600 760 10.0 -10.0 -30.0 Pressure (torr) 1 Boiling Points and Vapor Pressure Background As a very general rule of thumb, the boiling point of many liquids will drop about 0.5˚C for a 10mmHg decrease in pressure when operating in the region of 760 mmHg (atmospheric pressure).

  • ESSENTIALS of METEOROLOGY (7Th Ed.) GLOSSARY
    ESSENTIALS OF METEOROLOGY (7th ed.) GLOSSARY Chapter 1 Aerosols Tiny suspended solid particles (dust, smoke, etc.) or liquid droplets that enter the atmosphere from either natural or human (anthropogenic) sources, such as the burning of fossil fuels. Sulfur-containing fossil fuels, such as coal, produce sulfate aerosols. Air density The ratio of the mass of a substance to the volume occupied by it. Air density is usually expressed as g/cm3 or kg/m3. Also See Density. Air pressure The pressure exerted by the mass of air above a given point, usually expressed in millibars (mb), inches of (atmospheric mercury (Hg) or in hectopascals (hPa). pressure) Atmosphere The envelope of gases that surround a planet and are held to it by the planet's gravitational attraction. The earth's atmosphere is mainly nitrogen and oxygen. Carbon dioxide (CO2) A colorless, odorless gas whose concentration is about 0.039 percent (390 ppm) in a volume of air near sea level. It is a selective absorber of infrared radiation and, consequently, it is important in the earth's atmospheric greenhouse effect. Solid CO2 is called dry ice. Climate The accumulation of daily and seasonal weather events over a long period of time. Front The transition zone between two distinct air masses. Hurricane A tropical cyclone having winds in excess of 64 knots (74 mi/hr). Ionosphere An electrified region of the upper atmosphere where fairly large concentrations of ions and free electrons exist. Lapse rate The rate at which an atmospheric variable (usually temperature) decreases with height. (See Environmental lapse rate.) Mesosphere The atmospheric layer between the stratosphere and the thermosphere.

  • Chapter Two Properties of Ammonia
    Chapter Two Properties of Ammonia Physical Properties General Anhydrous ammonia exists as either a colorless gas, colorless liquid, or white solid, depending on its pressure and temperature. In nearly all commonly encountered situations, it exists as either a liquid or a gas. The gas is less dense than air and the liquid is less dense than water at standard conditions. Ammonia gas (vapor) diffuses readily in air and the liquid is highly soluble in water with an accompanying release of heat. Ammonia exhibits classical saturation relationships whereby pressure and temperature are directly related so long as both the vapor and liquid phase are present. It does have a critical pressure and temperature. At atmospheric pressure, a closed container of ammonia vapor and liquid will be in equilibrium at a temperature of –28°F [–33°C]. It should be noted however that if liquid ammonia is spilled or released to the atmosphere at normal temperatures, the resultant pool of boiling liquid will be significantly colder than –28°F due to the law of partial pressures (the partial pressure of the ammonia vapor in the air near the liquid surface will be less than atmospheric pressure). The following table provides some of the important physical properties of ammonia.

  • Liquid Nitrogen Safety
    Michigan Technological University, Department of Physics Liquid Nitrogen Safety Adapted from Department of Chemical Engineering Safety Manual and: http://engineering.dartmouth.edu/microengineering/ln2.html Properties of Liquid Nitrogen (LN2) 1. It is extremely cold: 77.3K = -196C = -320F at atmospheric pressure. This can cause severe frost bite 2. On vaporization it expands by a factor of 700; one liter of liquid nitrogen becomes 24.6 cubic feet of nitrogen gas. This can cause explosion of a sealed container, or it can displace oxygen in the room and cause suffocation without warning. 3. It can become oxygen enriched and cause ordinarily noncombustible materials to burn rapidly. Personal Protection When Handling LN2 1. When handling LN2 you should maximize the protection offered by clothing. Wear full sleeves, long pants and non-porous closed-toe shoes. 2. Splashing is common, so safety goggles or a face shield should be worn at all times when working with LN2. 3. Wear protective gloves when touching any object cooled by liquid nitrogen. However, the gloves should be loose fitting, so they could be thrown off if liquid were to pour inside them. 4. Care must be taken to prevent uninsulated containers from contacting unprotected skin since they may become bonded to the skin and will serious injury. 5. Contact of the skin with LN2 can cause severe cryogenic burns (tissue damage is similar to frostbite or thermal burns). Although small amounts of LN2 quickly evaporate when on the skin surface, if the liquid becomes trapped under jewelry, watches, or inside gloves or folds of clothing, it can result in serious and painful burns.
