Expert Answer:

Heat is flow of energy from body at higher temperature to body at lower temperature. Thus, on heating the hot object the heat energy will flow from the hot object to our hand. Thus, the heat is evolved by the object and our hand absorbs the heat energy. Due to this flow of energy, we sense the hotness of an object with our hand.
