1) Define Internal Energy
Answers
Answer:The internal energy of a thermodynamic system is a measure of the energy within it, excluding the kinetic energy of motion of the system as a whole, and the potential energy of the system as a whole due to external force fields. It keeps account of the gains and losses of energy of the system that are due to changes in its internal state. The internal energy is measured as a difference from a reference zero defined by a standard state. The difference is determined by thermodynamic processes that carry the system between the reference state and the current state of interest.
