5. a measure of the size of a body or region in three-dimensional space
6. the change of state from a gas to a liquid
7. the change of state in which a solid becomes a liquid by adding heat
9. the physical forms of matter which include solid, liquid, and gas
10. the process in which energy is being removed from a substance
12. the change of a substance from liquid to a gas
14. the law that states the volume of a gas is directly proportional to the temperature of a gas when pressure is constant
16. the process in which a solid changes directly into a gas
22. the amount of force exerted per unit area of a surface

1. the priniple that states the pressure in a fluid decreases as the fluids velocity increases
2. the change of a substance from one physical state to another
3. the coversion of a liquid to a vapor when the vapor pressure of the liquid equals the atmospheric pressure
4. a measure of how hot or cold something is
8. when energy is being transferring into something
