WebJan 31, 2024 · Sorted by: 1. To cool a gas reversibly, what you do is put the gas into contact with not just one, but with a sequence of constant temperature reservoirs, each one at a slightly lower (i.e., differentially lower) temperature than the one before. This allows both the gas and the sequence of reservoirs to experience a reversible change. WebFeb 20, 2024 · In equation form, the first law of thermodynamics is. (15.1.1) Δ U = Q − W. Here Δ U is the change in internal energy U of the system. Q is the net heat transferred into the system —that is, Q is the sum of all heat transfer into and out of the system. W is the net work done by the system —that is, W is the sum of all work done on or by ...
