What are the properties of bodies that determine how much heat is released when they cool down, or how much heat must be added to them to raise their temperature? Think about it. Answer the questions.
So, in heat transfer, heat is transferred from one body to another. Bodies are different, but do different bodies transfer different amounts of heat to other bodies when they cool? What properties of the body does this depend on? In physics we try to build models. Here, it is almost possible to build a physical model.
