Question

A perfect gas at ${27}^{\circ }C$ is heated at constant pressure to ${327}^{\circ }C$. If original volume of gas at ${27}^{\circ }C$ is V then volume at ${327}^{\circ }C$ is

• A. V
• B. 3V
• C. 2V
• D. V/2

Answer 1

The correct option is C 2V

From Charle’s law $V\infty T\therefore \frac{V_2}{V_1}=\frac{T_2}{T_1}=\frac{327+273}{27+273}=\frac{600}{300}=2\Rightarrow V_2=2V.$
