Across 9. occurs because particles in matter are in constant motion 10. Change in thermal energy= mass X Change in temperature X specific heat = M(tf-Ti)C 11. A material which heat flows 12. Thermal Energy that flows from something at a higher temperature to something at a lower temperature

Down 1. Of an object is a measure of the average kinetic energy of the particles in the object 2. These two are related 3. Energy transferred by radiation 4. The sum of the kinetic and potential energy of all the particles in an object 5. Amount of heat needed to raise the temperature of 1kg of some material by 1 C 6. The transfer of energy by electromagnetic waves 7. The transfer of thermal energy in a fluid by the movement of warmer and cooler fluid from place to place 8. the transfer of thermal energy by collisions between particles in matter
