The gas constant conveniently gives us the volume in "litres". Note here that I have (i) converted the pressure in "Torr", and (ii) converted the temperature to "degrees Kelvin", which are typically used in these reactions. Aug 29, 2006 · The gas temperatures are 620 ± 40 K near the substrate (z = 2 mm) and 670 ± 40 K in the hollow (z = 6 mm) at a discharge operated at P VHF = 5 W cm −2, T sub = 473 K and p = 9.3 Torr. The gas temperature is ≈ 150 K higher than the temperature of the substrate electrode. The specific gas constant for air is R air=287 J/kgK and the specific heat capacity at constant pressure c p=1 J/gK Solution: We first calculate the mass of air in each side of tank: 6 10 0.5 287 / 400 2.613 1210 0.2 287 / 500 1.672 Since tank is rigid and its volume remains constant, there is no work for volume change.
