Cool Latent Heat Of Vaporization Formula
M 145 grams.
Latent heat of vaporization formula. Is defined through the formula Q mL. 2 Enthalpy of vaporization. Specific latent heat is characterized as the measure of heat energy heat Q that is consumed or discharged when a body experiences a steady temperature process.
Class 9 Chemistry Matter In Our Surroundings. The enthalpy of vaporization is a function of the pressure at which that transformation takes place. The heat of water vaporization is the most well-known.
Let us calculate latent heat by a simple expression. Given parameters are 2257 joule per gram. 1 Increase in volume during vaporization.
For ex the latent heat of fusion of water or ice is 335kjkg and this should be multipied by mass of substance to get fixed amount of heat required for phase change. Determine the latent heat of a 10kg substance if the amount of heat for a phase change is 200kcal. According to its phase it has different names like the heat of condensation the heat of vaporization etc.
E m L For phase change. If the heat of vaporization for water is 2257 joule per gram. For isobaric vaporization the added heat of vaporization process quantity leads to a change in the enthalpy of the substance state variable.
This means that 226 x 105 J of heat energy must be added to turn one kilogram of water from liquid to gas at 100 degrees Celsius. M is the mass of a. Is often just called the latent heat of the material.
