Across 5. Energy transfered from one molecule to another because of difference in kinetic energy. 8. Decrease in temperature observed when a compressed gas expands rapidly 9. Chemical reaction or physical change that releases heat 11. Basic unit in metric system for measuring temperature represented as C 13. Process by which liquid water becomes a gas 14. Material that does not transfer heat easily or slows transfer of heat. 15. Measure of kinetic energy of molecules 16. Unit in English system for measuring temperature. The method that we use in the U.S. 17. energy of motion

Down 1. Energy is neither created or destroyed. it simply changes form 2. particle of matter 3. chemical reaction or physical change that absorbs heat 4. A change in which no new substance is produced, but the original substance changes form 6. Scientific tool that measures temperature in degrees C and F 7. Process in which one or more substances interact to form a new substance 10. Heat transfer through waves that move in all directions. 11. Heat transfer through liquids and gases where the matter is heated to a uniform temperature. 12. Heat transfer through direct contact
