Question

If you feel warm after exercising, have you increased the internal energy of your body? Explain.

Answer

"If we are feeling warm after exercising, it is indicative of an increase in the surrounding temperature. The release of heat from our body is a transfer of energy from the system to the surroundings, resulting in a decrease in the internal energy of our body. The internal energy, denoted as U, comprises of the sum of the kinetic energy from molecular motion and the potential energy from vibrational and electric motion of atoms within a system or body with clearly defined limits. The energy contained in a chemical bond is referred to as internal energy. Internal energy can take on a variety of forms from a microscopic perspective and is a significant state function of a system that is influenced by the substance or chemical attraction between molecules. Specific internal energy, represented by the lowercase letter U, is an intense thermodynamic characteristic that is measured in J/g as the internal energy per mass of the substance in question. Alternatively, the unit J/mol can be used to express internal energy as a function of the quantity of substance under consideration.
