High heat of vaporization example
WebOne of the most common real-life examples of evaporation is drying of clothes under the sun. When the wet clothes are put under the sun, they get heated up resulting in the evaporation of water particles present in wet … WebHeat of vaporization refers to the energy required to convert one gram of liquid into a gas at boiling point. This required energy will break down the intermolecular attractive forces in water. At 100oC, which is the boiling point of water, water has a heat of vaporization equal to 2260 J/g. This means that 2260 J of heat is needed in order to ...
