Why do think the heat of vaporization for water is so much larger than the heat of fusion?
Fusion is the process of joining two elements together to make a heavier element (as in the hydrogen bomb). The energy released by fusion is fare larger than the energy required to vaporise water - the two processes just can not be equated.
I suspect you have your question muddled up.
What else can I help you with?
Is energy released or absorbed when water changes state from a solid to a liquid to a gas?
Energy is absorbed when water changes state from a solid to a liquid to a gas. This energy is used to break the bonds between water molecules during melting and vaporization. It is known as the latent heat of fusion and latent heat of vaporization, respectively.
What is the heat of vaporization value of water?
The heat of vaporization of water is approximately 2260 J/g at a temperature of 100°C. This means that it takes 2260 Joules of energy to convert 1 gram of liquid water into vapor at its boiling point.
How many btus are requiier to change five pounds of ice 20f to steam at 220f?
To change 5 pounds of ice at 20°F to steam at 220°F, you would first need to heat the ice to its melting point, then heat the water to its boiling point, and finally convert the water to steam. The total heat required can be calculated using the specific heat capacities of ice, water, and steam, as well as the heat of fusion and vaporization. The specific calculations would depend on the specific heat capacities and heat of fusion/vaporization values provided.
What information can be found in a water heat of vaporization table?
A water heat of vaporization table provides data on the amount of energy required to change a unit mass of liquid water into vapor at a specific temperature.
How much energy is needed to change 1 gram of ice to 1 gram of steam?
Assuming atmospheric pressure, ice of 0oC and steam of 100oC? This equals the heat of fusion + the specific heat of water * 100 + the heat of vaporization At 1 bar (rougly 1 atm): heat of fusion = 333.55 j/g specific heat = 4.186 j/(g*k) * 100 = 418.6 j/g heat of vaporization = 2257 j/g So 333.55 + 418.6 + 2257 = 3009.15 joules required.
What requires more energy the latent heat vaporisation of water or the latent fusion of ice?
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.
What is the difference between heat of fusion and heat of vaporization?
Latent heat is the amount of thermal energy required to change the phase of a substance. Latent heat of fusion is the amount of energy needed to change it from a solid to liquid or a liquid to solid, and the latent heat of vaporization is the thermal energy needed to change from a liquid to gas or a gas to liquid. For example, in the equation Q = mL, Lfusion (latent heat of fusion) for water is 75.5 cal/gram. Lvaporization (latent heat of vaporization) for water is 539 cal/gram. Substances have different latent heats.
What specific heat is the energy used to evaporate water or melt snow?
The specific heat of water is the amount of energy required to raise the temperature of water by 1 degree Celsius. The heat of vaporization is the energy required to change water from a liquid to a gas (steam) at its boiling point. The heat of fusion is the energy required to change water from a solid to a liquid (melt snow) at its melting point.
Which phase change reguires water to gain 2260 joules per gram?
vaporization
Is energy released or absorbed when water changes state from a solid to a liquid to a gas?
Energy is absorbed when water changes state from a solid to a liquid to a gas. This energy is used to break the bonds between water molecules during melting and vaporization. It is known as the latent heat of fusion and latent heat of vaporization, respectively.
Which biological process uses the latent heat vaporization of water?

What is the heat of vaporization of water in joules per kilogram?
The heat of vaporization of water is 2260 joules per kilogram.
How much heat is necessary to vaporize 500 grams of ice at its freezing point?
The heat required to vaporize 500 grams of ice at its freezing point is the sum of the heat required to raise the temperature of the ice to its melting point, the heat of fusion to melt the ice, the heat required to raise the temperature of water to its boiling point, and finally the heat of vaporization to vaporize the water. The specific heat capacity of ice, heat of fusion of ice, specific heat capacity of water, and heat of vaporization of water are all needed to perform the calculations.
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 do you use the word vaporization in a sentence?
Vaporization of water eventually results in the formation of clouds.
An example of vaporization?
If you think of an ice cube (a solid) in the sun, it melts to water (a liquid) and the water heats up by the sun and goes in the air, which makes the water a gas
What is water as a gas?
vaporization water vapour Steam
