Statement I: The final temperature of an ideal
gas in adiabatic compression is less in reversible
compression than in irreversible compression
against a constant external pressure.
Statement II: The magnitude of work done on
an ideal gas in adiabatic compression is more in
irreversible process than that in reversible process.
gas in adiabatic compression is less in reversible
compression than in irreversible compression
against a constant external pressure.
Statement II: The magnitude of work done on
an ideal gas in adiabatic compression is more in
irreversible process than that in reversible process.
View answer and explanation
Correct option: A
If both statements are CORRECT, and Statement II is the CORRECT explanation of Statement I
Option A is correct. Irreversible adiabatic compression results in a higher final temperature and more work done compared to reversible adiabatic compression because energy is dissipated as heat in the irreversible process.

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
