Delta U, a measure of the change in internal energy of a system, is closely related to enthalpy, heat capacity, specific heat, and calorimetry. Enthalpy represents the total thermal energy of a system including internal energy and pressure-volume work, while heat capacity measures the ability of a substance to absorb heat without a significant temperature change. Specific heat quantifies the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius. Calorimetry is the study of heat transfer and involves measuring changes in delta U and other thermodynamic properties.
