What is the heat of vaporization of water in joules per kilogram?

The heat of vaporization of water is 2260 joules per kilogram.


A sample of H20 with a mass of 46.0 grams has a temperature of 100 c How many joules of energy are necessary to boil the water?

The heat of vaporization is about 2258 joules/gram46 x 2258 = 103,868 J ~ 103.9 kJ(Using the rounded value 2260 joules per gram, about 104 kJ)it is already at boiling point so in theory zero energy is required.I think the question is asking what energy is required to free the water from its liquid state to the vapour state.At 101325Pa, (1 atmosphere in old money), the latent heat of evaporation of water is 2256.7 J/g.So 2256.7 * 46 = 103808 Joules


How many joules of heat are needed to completely vaporize 24.40 grams of water at its boiling point?

The heat of vaporization of water is 40.79 kJ/mol. First, determine the number of moles in 24.40 grams of water. Then, convert moles to joules using the molar heat of vaporization. This will give you the amount of heat needed to vaporize 24.40 grams of water.


Which process requires water to gain 2260 Joulesof energy per gram?

The process of vaporization, where water changes from liquid to gas, requires 2260 Joules of energy per gram to occur.


How much energy is required to vaporize 2kg of water at 100c?

Oh, dude, to vaporize 2kg of water at 100°C, you'd need about 2260 kilojoules of energy. It's like making a really intense cup of tea, but instead of sipping it, you're just turning it into steam. So, yeah, it's a pretty hot process, literally.

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 ).


When water vapor condenses how much heat is released into the atmosphere?

When water vapor condenses, it releases the latent heat of vaporization, which is around 2260 joules per gram. This heat energy warms the surrounding air as it is released during the condensation process.


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 many calories of heat is released when one gram of water vapor condenses into liquid water?

When one gram of water vapor condenses into liquid water, it releases about 2260 joules (540 calories) of heat energy. This process is called the latent heat of vaporization.


What is the specific heat of water in joules per kilogram degree Celsius?

The specific heat of water is 4186 joules per kilogram degree Celsius.


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 value of latent heat of vaporization of water?

The latent heat of vaporization of water is approximately 2260 kJ/kg at standard atmospheric pressure and temperature. This is the amount of energy required to change 1 kg of liquid water at its boiling point into steam at the same temperature.


What is the purpose of the water trap in determining the latent heat of vaporization of water?

The water trap is used to prevent any water vapor from escaping the system during the experiment. This ensures that the heat energy needed to vaporize the water is accurately measured, allowing for the determination of the latent heat of vaporization of water.


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 Latan heat of vaporisation of water?

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.
