2. The energy a substance must absorb in order to change from a liquid to a gas (88)
3. A change in which a system absorbs energy from its surroundings (86)

6. A change in which a system releases energy to its surroundings (86)
7. The energy a substance must absorb in order to change from a solid to a liquid (86)
8. A material has a definite volume but not a definite shape (69)
