- 1. means that when matter is heated up it expands
- 2. any object that has mass and takes up space
- 3. the amount of energy needed to change a material from the liquid state to the gas state
- 6. states that if you decrease the volume(amount of space) of a container of gas, the pressure of the gas will increase
- 8. the amount of force matter pushes on an amount of space
- 10. states that the volume of a gas increases with increasing temperature
- 11. is an object's mass compared to it's volume
- 15. a gas like mixture of charged particles that move very fast due to the extreme amount of heat energy
