High heat of vaporization example
WebNext, the outer skin 122 may play a role of preventing liquid droplets from being generated and transferring heat from the heating element 14 to the core part 121 to ensure smooth vaporization. For example, the outer skin 122 suppresses the liquid phase 111 absorbed as bubbles rapidly grow inside the core portion 121 from being rapidly pushed ... WebHeat of vaporization definition, the heat absorbed per unit mass of a given material at its boiling point that completely converts the material to a gas at the same temperature: equal to the heat of condensation.
