The work done during the process when 1 mole of gas is allowed to expand freely into vacuum is:
View answer and explanation
Correct option: A
Zero
Option A (Zero) is correct because when a gas expands freely into a vacuum, the external pressure is zero, resulting in no work being done.

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
