Which of the following best describes the first law of thermodynamics?ResponsesEnergy always changes from a more useful, more concentrated form to a less useful, less concentrated form.Energy always changes from a more useful, more concentrated form to a less useful, less concentrated form.In a closed system of constant mass, the energy involved in any physical or chemical change is neither created nor destroyed, but merely changed from one form to another.In a closed system of constant mass, the energy involved in any physical or chemical change is neither created nor destroyed, but merely changed from one form to another.Heat always flows from a hot body to a cold body.Heat always flows from a hot body to a cold body.Entropy of a system increases as the state of disorganization in the system increases.Entropy of a system increases as the state of disorganization in the system increases.In a reversible process, the entropy of the system is constant, whereas in an irreversible process, the entropy of the system increases.
