Materials can be classified as solids, liquids, or gases based on whether their shapes and ____________________ are definite or variable. 3. The shape of a material remains constant when it is moved from one container to another. This material is a(an) ____________________. 4. The ____________________ theory of matter states that all particles of matter are in constant motion. 5. The motion of one particle of a gas is unaffected by the motion of other particles of the gas unless the particles ____________________. 6. ____________________ between the particles of a gas and the walls of the container cause pressure in a closed container of gas. 7. The pascal is the SI unit for ____________________. 8. Reducing the volume of a gas ____________ its pressure if the __________ of the gas and the number of particles are constant. 9. A graph representing Charles’s law shows that the ____________________ of a gas increases at the same rate as the ____________________ of the gas. 10. The combined gas law describes the relationship among the ___________, ___________, and __________ of a gas when the number of particles is constant. 11. If you are using Charles’s law to find the volume of a gas at a certain temperature, the temperature must be expressed in ____________________. 12. If you know the volume and pressure of a gas and the pressure changes, you can find the new volume by multiplying P1 by V1 and ____________________ this number by P2. 13.

Evaporation is the process that changes a substance from a liquid to a gas at temperatures below the substance’s ____________________ point. 17. During a(an) ____________________ change, the system releases energy to its surroundings. Short Answer 18. Solid, liquid, and gas are three states of matter.What are two other states of matter, and under what conditions do they exist? 19. If a gas has a volume of 1 L at a pressure of 200 kPa, what volume would it have when the pressure is increased to 400 kPa? Assume the temperature and number of particles are constant.
