  1. 1. What the scientist measures in an experiment
  2. 2. Light energy hits a surface and converts into heat energy
  3. 3. Compares the amount of matter an object has to its volume
  4. 5. A form of heat transfer where energy is directly transferred between molecules through molecular collisions or direct contact
  5. 9. A measure of how hot or cold something is; specifically, a measure of the average kinetic energy of the particles in an object
  6. 12. The state of matter that has a definite volume but not a definite shape
  7. 14. The change of state from a gas to a liquid - when a cold surface meets warmer air
  8. 16. Matter can leave from or escape to the surroundings
  9. 17. A substance that reduces the transfer of thermal energy
