A flask containing air at $27\,^oC$ at atmospheric pressure is corked up. A pressure of $2.5\,atm$ would force the cork out. The temperature at which it happens is

A

$67.5\,^oC$

B

$750\,K$

C

$577\,^oC$

D

$670\,K$

Solution

$\frac{P_{1}}{T_{1}}=\frac{P_{2}}{T_{2}}$

Here $P_{1}=1, P_{2}=2.5, T_{1}=300 \mathrm{K}$

This gives $T_{2}=750 \mathrm{K}$
