Unformatted text preview: 2g h2 = R T2 We have 2 equations and 3 variables (h1, h2, T2) so we need one more equation. The missing equation is the 1st law of thermodynamics, i.e., the energy conservation. This states that the potential energy of the weight plus the energy of the gas remains constant, since no heat is exchanged between the gas and its surroundings: m2g h2 + T2 = m2g h1 + T1 We have assumed that is temperature ­independent.
