latent heat of vaporazition?

Answer 1

Latent Heat of Vaporisation

A Surprising properties of solvents

For example

You are heating a tub of water which is at 30 degree cel

What you will see is it's temp will raise continuously

but at 100 deg it will start vaporising but the temp will not raise

Then where all the heat is going, it is consumed by the water to convert itself from liquid state to vapor state .

So the acceptance of the heat by a solvent whithout raising in its temp to vaporise is called Latent heat of vaporisation.

Answer 2

This is the basic principal of refrigeration units. When a substance evaporates, it absorbs heat - this heat is released when the substance condenses back into a liquid.

A good example of this is when you boil water on a stove. As the water boils, the flame under the pan continues to add heat to the water - yet the temperature of the water remains constant. This "latent heat" is absorbed by the water vapor as it evaporates. This heat will be given off when the water condenses on a cooler surface.

The "evaporator" in a refrigeration unit absorbs the heat from the objects inside of it and gives this heat off in the "condenser" unit. A compressor simply recycles the refrigerant in a closed system to keep this process on going.
The amount of heat needed by a substance usually in liquid form to convert to gas.The transformation occurs at a point called boiling point usually gaged by temperature.This is actually not heat as we use in daily word,but energy because it involves no difference in temperature.

Find a book call Introduction to Theory of Thermodynamics and make sure it has a chapter on latent heat of Vaporisation.
