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

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
