Heat of vaporization is mainly of two types: evaporation and boiling. Latent heat of vaporization – water at 3 MPa (pressure inside a steam generator) h lg = 1795 kJ/kg The units are cal/gram and values for the heat of vaporization of water at different temperatures are given in Table 3.1. The enthalpy of vaporization, (symbol ∆H vap) also known as the (latent) heat of vaporization or heat of evaporation, is the amount of energy that must be added to a liquid substance, to transform a quantity of that substance into a gas.The enthalpy of vaporization is a function of the pressure at which that transformation takes place.. Latent heat of vaporization – water at 3 MPa (pressure inside a steam generator) h lg = 1795 kJ/kg The experimental data shown in these pages are freely available and have been published already in the DDB Explorer Edition.The data represent a small sub list of all available data in the Dortmund Data Bank.For more data or any further information please search the DDB or contact DDBST.. Similarly, while ice melts, it remains at 0 °C (32 °F), and the liquid water that is formed with the latent heat of fusion is also at 0 °C. How much energy is required to completely vaporize the water? As a result of the network of hydrogen bonding present between water molecules, a high input of energy is required to transform one gram of liquid water into water vapor, an energy requirement called the heat of vaporization. 1 mole of water requires 40.66 kJ/mol heat to boils at its boiling point. This is due to a change in the exposed surface area of the water. Get more help from Chegg. The term “molar heat of vaporization” is sometimes applied to the heat of vaporization per mole. The enthalpy of vaporization is a function of the pressure at which that transformation takes place. Write your answer in the space below and click on the check button. Latent heat of vaporization – water at 0.1 MPa (atmospheric pressure) h lg = 2257 kJ/kg. Latent heat of vaporization – water at 3 MPa (pressure inside a steam generator) h lg = 1795 kJ/kg The heat of vaporization is a latent heat. See Example #3 below. What does this imply physically about the difference of a phase change of a molecular solid to a liquid and the phase change of a molecular liquid to a gas? Enthalpy of vaporization is a function of the pressure at which the transformation from one state to other occurs. Get 1:1 help now from expert Physics tutors The heat of fusion for water at 0 °C is approximately 334 joules (79.7 calories) per gram, and the heat of vaporization at 100 °C is about 2,230 joules (533 calories) per gram. The heat of vaporization of water is almost seven times its heat of fusion. Table 1 gives the values of the heat of vaporization per kg L v for several substances at normal external pressure (760 mm Hg, or 101,325 newtons per m 2 ) and at the boiling point t b . Mass of water, m = 2.98 g The enthalpy of vaporization is a function of the pressure at which that transformation takes place. In seawater: Thermal properties …energy known as the latent heat of vaporization is required to break the hydrogen bonds. heat: kJ

The heat of vaporization of water at 100 ºC is 2260 J/g. The enthalpy of vaporization is a function of the pressure at which that transformation takes place. How much heat is absorbed when 3.42 g of water boils at atmospheric pressure? Heat of vaporization is amount of heat which converts water from liquid state to the vapour phase. 1.
