Question

what is the definition of heat transfer?
oa a form of energy due to the hotness or coldness of matter
ob a measure of the average kinetic energy of the particles in matter
oc the movement of energy via particle motion from matter with a higher temperature to matter with a lower temperature
od the movement of energy via particle vibration from matter with a lower temperature to matter with a higher temperature

Explanation:

Heat transfer is the movement of thermal energy from a region of higher temperature to a region of lower temperature. Option A describes thermal energy, not heat transfer. Option B is the definition of temperature. Option D is incorrect as heat moves from high - to low - temperature regions. Option C correctly defines heat transfer as the movement of energy via particle motion from matter with a higher temperature to matter with a lower temperature.

Answer:

C. the movement of energy via particle motion from matter with a higher temperature to matter with a lower temperature
