Question

The pressure and absolute temperature of a certain mass of a gas whose volume $V$ is doubled. The new volume of the gas is:

• A. $\frac{V}{2}$
• B. $2V$
• C. $V$
• D. $4V$

Answer 1

The correct option is C $V$

The pressure and absolute temp. of a certain mass of a gas whose volume $V$ is doubled. The new volume of the gas is $V$.

$V\propto \frac{T}{P}$.

Thus, when both temperature and pressure are doubled, their ratio remains unchanged.

Hence, the volume remains unchanged.

Hence, the correct answer is option $\text{C}$.
