Question
If one mole of H2 gas is occupies a rigid container with a capacity of 1000 litres and the temperature is raised from 27°C to 37°C, 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)
Answer :
83.14
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 = 83.14 Pa
