Boiling is the phase transformation of a substance from a liquid to a gas . Thermodynamics defines entropy ($S$) as a measure of the degree of randomness or disorder within a system . Among the states of matter, the gaseous state is the state of highest entropy because of the increased chaotic motion of particles compared to the liquid state . Consequently, the transition from liquid to vapour during boiling is accompanied by a significant increase in entropy . Furthermore, at the boiling point, the liquid and gas phases are in dynamic equilibrium, where the change in Gibbs free energy is zero ($\Delta G = 0$), making an increase in free energy incorrect .
