<p> Chapter 5 Study Guide</p><p>5-1 Matter- anything that has mass and takes up space</p><p>Volume- amount of space taken up by object; liquid volume measured in mL using a graduated cylinder; volume of irregular object found by water displacement</p><p>Weight- measure of gravitational force on object; measured in Newtons</p><p>Mass- amount of matter (stuff) in an object; mass measured in grams or kilograms using a triple beam balance</p><p>Inertia- resistance of object to change its motion (lazy); example- in a moving car you tend to keep moving until seatbelt catches you The more the mass the more the inertia. Ex. Big transfer truck harder to stop moving</p><p>Weight vs. Mass- weight can change depending on gravity, but mass stays the same anywhere in the universe (unless you remove some of the matter).</p><p>5-2 Density- amount of matter in a given amount of space (mass/volume); density of water is 1 g/mL. If an object is less dense than water (1g/mL) it will float; if it is more dense it will sink.</p><p>If several liquids separate in layers in a graduated cylinder, the most dense one would be on the bottom and the least dense one would be on the top.</p><p>Know how to use the density formula. D= m/v</p><p>Physical property- a property that does not change the matter’s identity Examples- color, size, shape, texture, conductivity, magnetism, solubility (dissolve), state of matter (solid, liquid, gas), density, ductile (wires), malleable (bendable), boiling or melting point, specific heat (how quickly heat up)</p><p>Physical Change- a change that does not form a new substance; matter always retains its identity Examples- melting ice, tearing paper, crushing a can, painting a bike, dissolving sugar </p><p>5-3 Chemical properties- describes matter on its ability to change into a new substance Examples- flammability (ability to burn), reactivity (ability to react chemically with other substances)</p><p>Chemical Change- change in which a new substance is formed Examples- milk sours, digestion, rocket blast, fireworks, burning wood, silver tarnishes, bake a cake, leaves change color in the fall</p><p>Signs of a chemical change- Change in color or odor Gas bubbles form Temperature changes Precipitate forms (solid falls out of solution)</p><p>** During a physical change the composition of the substance stays the same; during a chemical change the composition of the substance changes.</p><p>5-4 Mallaeability and conductivity are useful in coinmaking.</p><p>Magnets are used in alarm system to complete the electrical circuit.</p><p>Electrical cords are covered with plastic to protect you from becoming shocked by the electricity.</p>
