People used to think that heat was some sort of weightless thing (called âcaloricâ) that moved from a hot object (the tea) to the cold object (my hand). But that didnât explain why, for example, two cold things can heat each other up when you rub them together. We now know that heat is a form of energy, created by the movement of molecules in an object. So, the most precise way to describe heat flow is this: The mug of tea was hot relative to my hand.
