First Law of Thermodynamics

Easy
If one mole of H₂ gas 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)
83.14 Pa(± 1 accepted)
Explanation
At constant volume, ΔP = nRΔT/V = (1×8.314×10)/1 = 83.14 Pa.
