Across
- 2. energy, stored energy due to the interactions between objects or particles
- 4. the measure of the average kinetic energy of the particles in a material
- 6. energy, the result of the motion of all the particles, and the distance and attractions between those particles in the system
- 7. object, the object that gains energy from the energy transfer
- 10. equilibrium, when the temperatures of materials that are in contact are the same
- 11. the transfer of thermal energy from one material to another by electromagnetic waves
- 13. the change in state from a liquid to a gas
- 15. the movement of substances from an area of higher concentration to an area of lower concentration
- 17. object, the object that provides energy for energy transfer
- 18. the transfer of thermal energy from a region of higher temperature to a region of lower temperature. Heat can also refer to the amount of energy transferred during this process
- 19. system, a system that does not exhange matter or energy with the environment
- 22. energy due to motion
- 23. the transfer of thermal energy by collisions between particles of matter
Down
- 1. an increase in a material's volume when the temperature is increased
- 3. insulator, a material through which thermal energy does not flow easily
- 5. the study of heat
- 8. movement in all directions and at different speeds
- 9. system, a system that exchanges matter or energy with the environment
- 12. heat, the amount of thermal energy it takes to increase the temperature of 1kg of material by 1 degree celsius
- 14. a decrease in a material's volume when the temperature is decreased
- 16. conductor, a material through which thermal energy flows easily
- 20. the process by which a gas changes to a liquid
- 21. the transfer of thermal energy by the movement of particles from one part of a material to another
