WebNov 23, 2015 · So why is Gibbs free energy zero for phase changes at constant temperature and pressure? It isn't necessarily. For example if you supercool liquid water to -10 degrees C, let the water freeze and do this in a way that the final state is solid water at -10 degrees C, the change in Gibbs free energy will be negative. This is a spontaneous … WebA phase change is a change from one state to another without a change in chemical composition. These changes are induced by the effects of temperature and/or pressure: The transitions are: Solid-to-liquid transition – melting Liquid-to-solid transition – freezing Liquid-to-gas transition – evaporation Gas-to-liquid transition – condensation WebThe amount of heat required to change from a solid state to a liquid state. b. heat of vaporization The amount of heat required to change from a liquid state to a gaseous state.
