initial state, then work is done on the gas in compressing it toB and heat must be taken from the gas to keep its temperatureconstant. Ex. 64. If the air in Ex. 61 were expanded adiabatically till itsvolume was trebled, what would be the external work done and whatwould be its loss of heat? The… … In this equation KvdT represents, as before, the increase inthe intrinsic energy of the gas, whilst dL represents the work ofmolecular separation and dU represents external or visible work.Some heat must be expended in separating even the molecules ofperfect gases, since they must have some…
