Statement - I: The final temperature of an ideal gas in adiabatic expansion is less in
reversible expansion than in irreversible expansion against a constant external pressure.
Statement - II: The magnitude of work done by an ideal gas in adiabatic expansion is more
in reversible process than that in irreversible process.
reversible expansion than in irreversible expansion against a constant external pressure.
Statement - II: The magnitude of work done by an ideal gas in adiabatic expansion is more
in reversible process than that in irreversible process.
View answer and explanation
Correct option: A
If both Statement-I and Statement-II are true, and Statement-II is the correct
explanation of Statement-I
explanation of Statement-I
Option A is correct because in reversible adiabatic expansion, the gas does more work, leading to a greater decrease in temperature compared to irreversible expansion, and Statement II correctly explains Statement I.

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?
For which of the process, ∆S is negative?
The work done by a weightless piston in causing an expansion ∆V (at constant temperature), when the opposing pressure, P is variable, is given by:
Assertion :- At constant pressure of the change work done is negative.
Reason :- During phase transition work done is always negative. For the reaction, at . Hence, is
