MCQ
The temperature of a gas at pressure $P$ and volume $V$ is $27°C.$ Keeping its volume constant if its temperature is raised to $927°C,$ then its pressure will be
  • A
    $2\,P$
  • B
    $3\,P$
  • ✓
    $4\,P$
  • D
    $6 \,P$
✓

Answer

Correct option: C.
$4\,P$
c
Using Charle’s law $\frac{{{P_1}}}{{{P_2}}} = \frac{{{T_1}}}{{{T_2}}}$

or ${P_2} = \frac{{{P_1}{T_2}}}{{{T_1}}}$ $ = \frac{{P(273 + 927)}}{{(273 + 27)}}$ $=4P$
