Question

Among the following statements, the correct statement is (A) Internal energy of a gas depends only on the state of the gas. (B) In an isothermal process change in internal energy is maximum. (C) Area under pressure-volume graph equals heat supplied in any process. (D) Work done is state dependent but not path dependent.

Tardigrade Admin · Accepted Answer

Internal energy of a gas is state dependent and path independent. In an isothermal process, temperature remains constant, therefore change in internal energy is zero. Area under pressure-volume graph is equal to the work done by the gas. Work done is both state and path dependent.
