What is a latent heat of water?

Latent heat is a form of internal or potential energy stored by evaporated or melted water. As ice melts or liquid water evaporates, the molecules change state — from a solid to a liquid, from a liquid to a gas, or from a solid directly to a gas.

What is the latent heat of vaporization of water of 1 kg?

The latent heat for vaporization for 1 kg water is 536 cal.

How do you calculate latent heat of evaporation?

Latent heat calculation The specific latent heat is different for solid to liquid transition and liquid to gas transition. For example, if we want to turn 20 g of ice into water we need Q = 20 g * 334 kJ/kg = 6680 J of energy. To turn the same amount of water into vapor we need Q = 45294 J .

What is meant by saying that the latent heat of vaporization of water is 22.5 * 10/5 J kg?

Latent heat of vaporization of water in 22.5 X 105 Joules / kg means the heat require to vaporise 1kg of water is 22.5X 105 Joules / kg .

What is meant by saying that latent heat of vaporization of water is 226 KJ kg?

Solution : This means that when one kg of water at its boiling point temperature changes into steam, 226 kj of heat is absorbed.

What is meant by saying that the latent heat of ice is 3.34 10j kg?

What is meant by saying that the latent heat of fusion of ice is 3.34 × 105 J/kg? The latent heat of fusion of ice is 3.34 × 105 J/Kg means that 3.34 × 105 J of heat is required to change 1 kg of ice into the water at its melting point at the same temperature.

What is latent heat of fusion and vaporization?

The latent heat of vaporisation is the heat energy required to change 1 kg of liquid to gas at atmospheric pressure at it’s boiling point. whereas. The latent heat of fusion is the heat energy required to change 1 kg of solid to gas at atmospheric pressure at it’s melting point.

What is the latent heat of vaporization of steam?

Latent heat of steam is defined as the amount of heat required to change a unit mass of waster from 100 degree Celsius to steam at the same temperature. The latent heat of Vaporization for steam is 2.26 * 106 J kg-1 or 540 Cal g-1.

What is the value of latent heat needed in evaporation process?

For the water substance at 1 atm and 100 °C (the boiling point of water at 1 atm), the latent heat of vaporization is 2.25 ÷ 106 J kg21.
