Solving for compression ratio adiabatic

WebThe adiabatic compression ratio in a carnot reversible cycle is 9, when the temperature iof the source is `227^(@)C`. Calculate the temperature of the sink. ... WebThe first law of thermodynamics relates the change in internal energy dU to the work dW done by a system and the heat dQ added to it. By definition, in an adiabatic process, the heat exchanged dQ = 0. Substituting this in the first law and rearranging gives. The second term is easy: the work done dW when a system changes its volume V by dV is PdV.

WebBottom line: whether the compression makes more liquid or more gas depends not just on p and T but also on the starting liquid/gas ratio. There's a special liquid/gas ratio at each T, and whichever phase beats that ratio gains further, compared to the special ratio, as the cylinder is compressed. It's sort of like economics.
