Heat and Measuring Temperature Heat is one of the forms of energy. For a molecule or compound, heat is the total energy of its atoms and molecules. Heat can directly be related to temperature. Objects having higher temperature have more energy than objects having a lower temperature. Do you know the devices used for measuring temperature? Let’s find . . .
