Calorimetry 1. Heat: Every substance is made up of molecules. These molecules are in a state of constant random motion and also have some force of attraction between them. Due to their constant random motion they possess molecular kinetic energy and due to the force of attraction between them they maintain a certain configuration and possess molecular potential energy. We are explicitly using the word molecular because these energies are internal to molecules and have no relation with Mechanical Kinetic and Potential Energies that we have studied in the Chapter Work, Energy and Power. The Sum of Molecular Kinetic Energy and Molecular Potential Energy is known as Internal/Thermal Energy. A hotter body has more Internal Energy Compared to a Cooler Body. When a hotter body is placed in contact with a cooler body , then Internal Energy flows from the hotter body to the cooler body until both the bodies reach thermal equilibrium (i.e attain the same temperature). The Internal Energy in Transit is known as Heat Energy.
