Q. If one mole of H2 gas occupies a rigid container with a capacity of 1000 litres and the temperature is raised from 27 oC to 37 oC, the change in pressure of the contained gas (round off to two decimal places), assuming ideal gas behaviour, is___________Pa. (R=8.314 J/mol·K)
Ans: 83.14
Sol:
V=Volume of rigid container
T1=Initial temperature of the gas
T2=Final temperature of the gas
P1V=nRT1
P2V=nRT2
(P2−P1)V=nR(T2−T1)
ΔP×1=1×8.314(37−27)
ΔP=83.14Pa
