When a gas filled in a closed vessel is heated by raising the temperature by $1 ° C$ , its pressure increases by $0.4 %$ The initial temperature of the gas is _____ $K$ .

Answer:

250.00

Solution:

From ideal gas equation, $P V = n R T$ , where, $n$ is amount of substance, $R$ is ideal gas constant and $V$ is volume.

In closed vessel volume remains constant.

So, $\frac{d P}{P} \times 100 = \frac{d T}{T} \times 100$

$0.4 = \frac{1}{T} \times 100$

$\Rightarrow T = 250 K$
