When a gas filled in a closed vessel is heated by raising the temperature by 1$^\circ$C, its pressure increases by 0.4%. The initial temperature of the gas is ___________ K.
Answer (integer)
250
Solution
<p>$PV = nRT$</p>
<p>So ${{dP} \over P} \times 100 = {{dT} \over T} \times 100$</p>
<p>$0.4 = {1 \over T} \times 100$</p>
<p>$\Rightarrow T = 250\,K$</p>
