Across
- 4. The movement of energy from a warmer object to a cooler object
- 6. Energy that is radiated or transmitted in the form of rays or waves or particles
- 7. The total energy of motion in the particles of a substance
- 8. A state of matter that has a definite shape & a definite volume
- 10. Movement of energy from one place or object to another
- 11. The change of state from a liquid to a gas
- 13. A state of matter with no definite shape or volume
- 15. What the scientist changes in an experiment (1IV)
- 19. Matter is not able to enter or leave a system
- 20. A small portion of matter
- 21. A change of energy from one form to another
- 22. A measure of the amount of matter in an object
Down
- 1. What the scientist measures in an experiment
- 2. Light energy hits a surface and converts into heat energy
- 3. Compares the amount of matter an object has to its volume
- 5. A form of heat transfer where energy is directly transferred between molecules through molecular collisions or direct contact
- 9. A measure of how hot or cold something is; specifically, a measure of the average kinetic energy of the particles in an object
- 12. The state of matter that has a definite volume but not a definite shape
- 14. The change of state from a gas to a liquid - when a cold surface meets warmer air
- 16. Matter can leave from or escape to the surroundings
- 17. A substance that reduces the transfer of thermal energy
- 18. Factor in an experiment that a scientist purposely keeps the same
