Question:medium

A gas expands isothermally and reversibly from a volume V to 2V. If the initial pressure is P, what is the final pressure?

Show Hint

In isothermal expansions, remember that \( PV = \text{constant} \). Use this to find the relationship between initial and final pressures and volumes.

\( \frac{P}{2} \)
\( \frac{P}{4} \)
\( 2P \)
\( P \)
