Computer Vapor Pressure and Heat of Vaporization

To Measure The Specific Latent Heat of Vaporisation of Water. Background Information: When a substance warms or cools, heat energy is transferred from or to the substance, and the substance changes temperature (up or down).

How to calculate the Heat of Vaporization? Yahoo Answers

Calculate the heat of sublimation of the substance by dividing the heat absorbed by the substance, as calculated in step 2, by the mass of substance in grams. For example, if 47.5 g of substance was placed in the calorimeter, then the heat of sublimation would be 27,100 / 47.5 = 571 J/g.

Vaporization phase change Britannica.com

For a liquid-gas transition, L is the specific latent heat (or specific enthalpy) of vaporization, whereas for a solid-gas transition, L is the specific latent heat of sublimation. If the latent heat is known, then knowledge of one point on the coexistence curve determines the rest of the curve. Conversely, the relationship between lnP and 1/T is linear, and so linear regression may be used to

In distillation, heat of vaporization values are needed to find the heat loads for the reboiler and condenser, and knowledge of the enthalpy of vaporization is required in the design of heat exchangers for vaporizing liquids. A modified Watson equation for the enthalpy of vaporization as a function of temperature is as follows.

Fire Sizing Latent Heat Of Vaporization - Relief Devices

If the heat of fusion for H 2 O is 333.5 kJ/kg, the specific heat capacity of H 2 O (l) is 4.18 J/(g*K), the heat of vaporization for H 2 O is 2257 kJ/kg, then calculate the heat required to convert 1.00 kg of H 2 O (s) with the initial temperature of 273 K into steam at 373 K. Hint: 273 K is the solid-liquid phase change temperature and 373 K is the liquid-gas phase change temperature.
