P propto T ⇒ T2=(P2/P1)× T1 ⇒ T2=(2 P/P)× (.273+20.)=2× 293 =586K=313° C

Q. The certain amount of gas is sealed in a glass flask at $1$ atmosphere pressure and $2 0^{\circ} C .$ The flask can with stand up to a pressure of $2$ atmosphere. Find the temperature to which the gas can be heated so that the flask doesn't break.

$51 3^{\circ} C$

$41 3^{\circ} C$

$31 3^{\circ} C$

$21 3^{\circ} C$

$P \propto T$
$\Rightarrow T_{2} = \frac{P _{2}}{P _{1}} \times T_{1}$
$\Rightarrow T_{2} = \frac{2 P}{P} \times (273 + 20) = 2 \times 293$
$= 586 K = 31 3^{\circ} C$
