2 Rules Everything off your desk Sit on your desk
After you answer a question sit in your chair Be quit One question per student (2 points each) Total grade is for everyone in the class Every time a rule is broken (-1) points

3 According to Charles’s law, when the temperature of a gas increases at constant pressure, its
a. volume increases. b. mass increases. c. volume decreases. d. particles move more slowly.

4 When an inflated balloon is exposed to cold air,
a. the temperature inside the balloon rises. b. the pressure inside the balloon rises. c. the volume of the balloon decreases. d. the volume of the balloon increases.

5 A graph of Charles’s law shows the relationship between
a. volume and density of a gas. b. volume and pressure of a gas. c. temperature and volume of a gas. d. temperature and pressure of a gas.

6 A graph that shows that the pressure of a gas varies inversely with its volume under constant temperature demonstrates a. the Pressure law. b. the Density law. c. Charles’s law. d. Boyle’s law.

7 A graph that shows that the volume of a gas is directly proportional to its temperature under constant pressure demonstrates a. the Pressure law. b. Charles’s law. c. the Density law. d. Boyle’s law.

8 A graph of Boyle’s law shows the relationship between
a. volume and density of a gas. b. volume and pressure of a gas. c. temperature and volume of a gas. d. temperature and pressure of a gas.

9 Data plotted on a graph results in a line that slopes upward from left to right. This graph tells you that a. when one variable increases, the other variable increases. b. when one variable increases, the other variable decreases. c. when one variable increases, the other variable remains the same. d. both variables are decreasing.

10 When the temperature of a gas at constant volume increases, its
a. volume increases. b. pressure decreases. c. pressure increases. d. volume decreases.

11 Which state of matter undergoes changes in volume most easily?
a. solid b. liquid c. gas d. frozen

12 According to Boyle’s law, when the pressure of a gas increases at constant temperature, its volume
a. increases. b. stays constant. c. decreases. d. increases, then decreases.

13 When the temperature of a gas decreases at constant volume, its
a. pressure increases. b. mass increases. c. pressure decreases. d. particles move faster.

14 During the process of sublimation,
a. a solid turns directly into a gas. b. a solid turns into a liquid. c. a gas turns directly into a solid. d. a liquid turns into a gas.

15 What is vaporization? a. a gas becoming a liquid b. a liquid becoming a solid c. a gas becoming a solid d. a liquid becoming a gas

16 In cold climates, the amount of snow on the ground may decrease even if the temperature stays below zero degrees Celsius. The process that best explains this event is a. condensation. b. sublimation. c. melting. d. evaporation.

17 The opposite of vaporization is called
a. condensation. b. sublimation. c. evaporation. d. freezing.

18 The state of matter in which particles are arranged in either a crystalline or an amorphous form is
a. liquid. b. gas. c. solid. d. fluid.
