The temperature of water with a heat vaporization of 2100 would be at its boiling point, which is 100 degrees Celsius at sea level. This is the temperature at which water transitions from liquid to vapor phase.
The latent heat of vaporization of water is 2260 kJ/kg at standard atmospheric pressure and a temperature of 100°C. This is the amount of energy required to convert 1 kg of liquid water into vapor at the same temperature.
The heat of evaporation, also known as latent heat of vaporization, is the amount of energy required to change a substance from liquid to gas at its boiling point without changing its temperature. This energy is used to overcome the intermolecular forces holding the liquid together.
The latent heat of vaporisation of water requires more energy. This is because on melting, the intermolecular bonds in water are only weakened whereas on boiling, the bonds are completely broken, which requires a larger amount of energy.
No, the latent heat of vaporization is not fixed and can vary depending on the substance. It represents the amount of energy required to change a unit mass of a substance from liquid to gas at a constant temperature and pressure.
The heat released when water condenses and changes to liquid form is called the latent heat of condensation. This heat is released because the water vapor loses energy as it transitions to a liquid state, leading to a release of thermal energy.
The heat energy released or absorbed during a change of state of water is called latent heat. This energy is used to break or form intermolecular bonds without changing the temperature of the substance.
this process is called evaporation. it occurs when the bonds break, due to the average amount of energy, the temperature, going up enough to provide the latent heat of vaporisation. the latent heat of vaporisation is merely the name of the energy amount that it takes to break the bonds.

Because as water evaporates it absorbs latent heat of vaporisation
Is the amount of energy required to change 1kg of liquid into gas with no temperature change.
The heat of evaporation, also known as latent heat of vaporization, is the amount of energy required to change a substance from liquid to gas at its boiling point without changing its temperature. This energy is used to overcome the intermolecular forces holding the liquid together.
It's all to do with the latent heat of fusion (melting(Ice to water), and the latent heat of vaporisation (boiling( Water to steam) Stands for any substance. It is because all heat created by the heater, will be used as energy to break the lattice holding the atoms in their state. Once the state is fully changed, the heat energy will then be used up by raising the temperature. More can be found here: http://en.wikipedia.org/wiki/Latent_heat

Because crude oil is a mixture of different chemicals - mainly hydrocarbons - that have different evaporation temperatures. Roughly speaking, when the crude is heated, its temperature rises until it reaches the lowest vaporisation temperature. The temperature then remains more or less steady as the heat input is used as the latent heat of vaporisation for the relevant compound. When [almost] all of that compound has evaporated, the temperature starts rising again until it reaches the next varorisation temperature, and so on.

When you step out of the shower, your wet skin evaporates water, which absorbs heat from your body, making you feel cold. As you dry off, less water evaporates, so less heat is lost, causing you to feel warmer. Even though the room temperature remains the same, your body's heat loss changes due to the wetness of your skin.
