a Entropy difference between two phases as a function of temperature. b Entropy-temperature (S-T) in a Carnot thermodynamic cycle. c Phase-change cooling cycle, that is significantly different from the Carnot cycle. Here solid lines denote quasi-static processes, whereas dashed line denotes out-of-thermal-equilibrium process.
