Why is water considered as high specific heat and latent heat of vaporization?

The latent heat of vaporization of a liquid is the amount of heat needed to change that liquid when at it's boiling point to a gas.
Hydrogen bonds are present between water molecules. These are strong intermolecular forces between the slightly negative oxygen atom in one water molecule and the slightly positive hydrogen atom in another water molecule. These bonds must be broken in order for the water to change from a liquid to a gas and requires a great amount of energy thus explaining water's high latent heat of vaporization.

∙ 14y agoTo convert water to vapor, the volume increases significantly; the water thus has to push against the air pressure.
Wiki User
∙ 12y agoIt has a high specific heat because it takes allot of energy to heat water. It has a high latent hit because it take allot of energy to vaporise water.
Wiki User
∙ 7y agoI suppose that this is due to association of water molecules by hydrogen bonds.

When trees transpire releasing gaseous water into the atmosphere they can absorb heat from their environment and cool it down. What property of water is responsible for this activity?
Latent heat of vaporization.
Amount of heat necessary to change the state of substance?
Heat of vaporization or enthalpy of vaporization. It is the additional energy, per unit mass, required after vaporization temperature (boiling point) is reached, to accomplish the change in state, from liquid to gas.
What information does the latent heat of fusion give?
latent heat of fusion tells us about the amount of energy that must be taken off from water at 00C to fuse it into ice at 00C . Actually this in this phase temperature remains constant and this energy is (either latent heat of fusion or latent heat of vaporization is the potential energy which is possessed by the states by their virtue.
What is the specific latent heat of fusion of mercury?
The specific heat temperature of mercury is 14 degrees Celsius. Comparably, the specific temperature of water is 417.9 degrees and air is 101 degrees.
What is the heat of vaporization value of water?
It is approximately 539.4 calories per gram.
What step changes liquid water to water vapor?
Vaporization is the change of liquid water to water vapor. Vaporization requires addition of the latent heat of vaporization to liquid water. The latent heat of vaporization supplies the liquid water molecules with enough energy to become vapor molecules. The latent heat of vaporization at 1.0 atmosphere pressure is about 1000 Btu per lbm ( 2260 kJ per kg ).
What is the value of latent heat of vaporization of water?
2260 kJ/kg
How your body cooled when you perspire?
Perspiration coats the outside of the skin with moisture (water). The water evaporates. Evaporation requires heat to be absorbed by the water (the latent heat of vaporization). Heat is removed from the body surface to provide the water with the latent heat of vaporization.
What is the purpose of the water trap in determining the latent heat of vaporization of water?
to prevent water from entering the calorimeter and allow only the gas.
Are swamp coolers effective?
the water's latent heat of vaporization is being pulled from the air, the water pulls heat from the room to undergo a phase change.
Which biological process uses the latent heat vaporization of water?
i think d...................... what you mean
How your body is cooled when you perspired?
When your body perspires, it is coating your body with sweat. When it is really hot out, the sweat evaporates, cooling your body by removing the sweat.
When trees transpire releasing gaseous water into the atmosphere they can absorb heat from their environment and cool it down. What property of water is responsible for this activity?
Latent heat of vaporization.
Swamp coolers are effective because?
the water's latent heat of vaporization is being pulled from the air, the water pulls heat from the room to undergo a phase change.
Perspiration cools the body because?
the water is using heat to undergo a phase change , the water's latent heat of vaporization is being pulled from your body
Amount of heat necessary to change the state of substance?
Heat of vaporization or enthalpy of vaporization. It is the additional energy, per unit mass, required after vaporization temperature (boiling point) is reached, to accomplish the change in state, from liquid to gas.
How much calories is needed to evaporate water?
latent heat
