Final answer:

Heat is the transfer of thermal energy between objects where it flows from higher temperature to lower temperature until equilibrium. Average kinetic energy of molecules influences the temperature of a substance.


Explanation:

Heat is the transfer of thermal energy between two bodies at different temperatures. When a higher temperature object is in contact with a lower temperature object, heat flows from the higher temperature object to the lower temperature object until equilibrium is reached. The average kinetic energy of molecules determines the temperature of a substance, with higher kinetic energy leading to higher temperatures.
