Question:

When ideal gas expands in vacuum, the work done by the gas is equal to:

Show Hint

Work done by a gas depends on external pressure. In a vacuum, no pressure is applied, so no work is done.

The Correct Option is C

Solution and Explanation

Step 1: Work done in expansion. In an ideal gas expanding in a vacuum, no external pressure is applied, and therefore no work is done by the gas. Work is defined as \( W = p \Delta V \), and since \( p = 0 \) in a vacuum, the work done is zero.
Step 2: Conclusion. Thus, the work done by the gas is zero.
