What is internal energy? How is the formula for this determined?
I see. Does the formula for internal energy change for different types of substances?
The formula for internal energy is the same for all substances, but the specific values of kinetic and potential energy will depend on the properties of the substance, such as its temperature, pressure, and composition. So, for example, the internal energy of a gas will be different from that of a liquid or a solid at the same temperature and pressure.
