systems a, b, and c are classical gases (not necessarily ideal), each with the same number of molecules n (or same number of moles n if you prefer), where n is constant. we can measure pressures and volumes pa, va; pb, vb; and pc, vc for each system. when a and b are in thermal equilibrium, our measurements show that their pressures and volumes satisfy: when a and c are in thermal equilibrium, we find where α, β, and γ are constants. ta of system a in terms of pa, va and constants ts of system b in terms of pb, vb and constants tc of system c in terms of pc, vc and constants a) express the temperatures: b) find the equation relating pb, vb and pc, vc that is satisfied when systems b and care in thermal equilibrium. c) which of these systems is an ideal gas?
