Which beat describes heat

I assume you mean which best describes heat.

The answer is The energy transferred between samples of matter because of a difference in their temperatures.

To explain this further, heat is total energy of an object, temperature is average energy. The change in temperature between two objects is called heat!

Think about transfers of heat in everyday terms: if you put an ice cube in your tea (I don't know, just bear with me), the cold does not transfer to the tea. The heat of the tea is transferred to the ice cube! And this is clearly a difference in heat.
