How does evaporation involve the storage of heat?
When the energy is required to vaporize liquid water, the molecules are highly agitated and brake free to become vapor through the state of latent heat of vaporization, then the energy is removed from the liquid and the temperature is reduced.
Latent heat of vaporisation decreases as pressure increases and becomes zoro at critical pressure i read . why it so?
As pressure increases the temperature required to vaporize water is less. So with increase in pressure there is decrease in temperature required to boil so latent heat also decreases.
What does the heat latent heat of vaporization measure?
The energy required to boil a substance
What is latent heat of sublimation?
When a substance is below the triple point, the equilibrium will be between solid and vapor rather than solid/liquid or liquid/vapor. Sublimation is the direct change from solid to vapor without any intermediate phase change. The latent heat of sublimation is the energy required to change a given quantity of solid into the vapor at equilibrium. It is analogous to (but not the same as) latent heat of melting (energy required to melt the solid to liquid) and latent heat of vaporization (energy required to change a liquid into a gas).
What energy is required to create a phase change without changing the temperature?
It is called the latent heat of vaporisation.
What information does the latent heat of vaporization give?
The energy needed to completely vaporize a mole of a liquid
What information does latent heat of vaporization give?
The amount of energy required to turn a more of a liquid into a gas - apex
What is the latent heat of sublimation?
No. Latent heat of vaporization is defined as the energy required to VAPORIZE 1 kilogram of a liquid completely at its boiling point. Latent heat of sublimation is the energy required to SUBLIME 1 kilogram of a solid completely into a gas at constant temperature. They're different. Note that the temperatures should be constant during the processes.

Why is energy required for phase change?
Latent energy as far as I remember

What does the latent heat of vaporization represent?
