Chemistry Thermodynamics JEE Main

An ideal gas is allowed to expand both reversibly and irreversibly in an isolated system. If is the initial temperature and is the final temperature, which of the following statements is correct?

(A)Correct
(B) for reversible process but for irreversible process
(C)
(D) for both reversible and irreversible processes

Answer: (A)

Solution

In an isolated system, both expansions are adiabatic (no heat exchange). A reversible adiabatic expansion does maximal work against an opposing external pressure at every stage, drawing that energy from the gas's internal energy and cooling it (). An
