When a gas filled in a closed vessel is heated by raising the temperature by 1°C1 ° C, its pressure increases by 0.40 . 4 % The initial temperature of the gas is _____ KK.

Correct answer

0

Step-by-step solution

From ideal gas equation, PV=nRTPV = nRT, where, nn is amount of substance, RR is ideal gas constant and VV is volume.

In closed vessel volume remains constant.

So, dPP×100=dTT×100\dfrac{dP}{P} \times 100 = \dfrac{dT}{T} \times 100

0.4=1T×1000 . 4 = \dfrac{1}{T} \times 100

⇒T=250K⇒ T = 250K
