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.
What is the energy absorbed by one gram of water as it changes from its liquid phase into water vapor known as?
The heat of vaporization. :D
How do you calculate the latent heat of vaporization?
Calculating the amount of water reacted is simple with a scale. As long as the mass of the water before evaporation is measured, one can find the amount of water evaporated simply by measuring the mass of the water after evaporation and taking the difference of the mass. To convert this to volume, simply divide the mass by the density of water (typically 1g/cm3).
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.
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 is the value of latent heat of vaporization of water?
2260 kJ/kg
Is heat of vaporization for water is equal to heat on condensation of water?
yes
What is water and heat of vaporization?
Heat of Vaporization id the amount of heat needed to transform a liquid into a gas while not raising its temperature.
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 ).
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.
How much heat does water release the when it evaporates?
The water heat of vaporization is 40,65 kJ/mol.
The amount of energy needed to change a material from a solid to a liquid is the heat of what?
The latent heat of evaporation
When water leaves a body of water after it is heated process is called?
The phase change of water into gas is vaporization. Vaporization in this example involves the liquid water absorbing heat (endothermically).
Does water have a low vapor pressure?
High heat of vaporization. It requires a great deal of energy to break the H bonds in water.
Why does sweat cool off the body?
Water has a high heat of vaporization
What is the heat of vaporization of nitrogen?
This value is depending on the temperature; read the link below for details.
How can you use vaporization in a sentence?
vaporization of water happens when it turns from a liqued form into a gas due to heat which creates conensation :P
