During the adiabatic compression (dα < 0) the internal energy increases dq = dupdα and dq = 0 =⇒ du = −pdα > 0 and therefore the temperature of the system rises du = cv dT > 0 =⇒ TC > TA However, for the isothermal compression from A to B, the temperature remains constant TB = TA Hence, TB < TC But αB = αC (the final volumes are equal);The adiabatic theorem is a concept in quantum mechanicsIts original form, due to Max Born and Vladimir Fock (1928), was stated as follows A physical system remains in its instantaneous eigenstate if a given perturbation is acting on it slowly enough and if there is a gap between the eigenvalue and the rest of the Hamiltonian's spectrum In simpler terms, a quantum mechanicalConsidering this substitution, can we say that heat absorbed in the isochoric process is equivalent to the work done in an adiabatic process?
