The latent heat of fusion of 1kg water is 334 kJ/kg. (Wikipedia)
The total pressure of water is calculated by adding the atmospheric pressure to the pressure due to the depth of the water column using the formula: total pressure = atmospheric pressure + (density of water × acceleration due to gravity × depth of water).
The saturation temperature of water at standard atmospheric pressure is 100 degrees Celsius.
The formula to calculate the latent heat of fusion is Lf = Q / m, where Lf is the latent heat of fusion, Q is the amount of heat added or removed during the phase change, and m is the mass of the substance undergoing the phase change.
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.
It's the latent heat of fusion. It varies between substances, for water, it's around 333 joules of energy per gram of water, about 80 calories per gram in the old money.
Latent heat of water is the heat required to change its state at a particular temperature BECAUSE of the pressure at which the water is at at the point of fusion or evaporation.The latent heat is not affected by temperature (in fact there is no temperature change during absorption of latent heat) it is affected by the pressure acting on a substance. As the pressure increases, the latent heat (of evaporation) decreases, consequently with the change in pressure there is also a different temperature at which the evaporation takes effect, higher pressure, higher temperature at the evaporation point.
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.

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.
When 1 mole of water freezes at 0°C under standard atmospheric pressure, the process releases approximately 6.01 kJ of energy as latent heat of fusion. However, the actual work performed during the phase change is negligible in this scenario because the volume change is minimal when water freezes. Thus, the work done can be considered to be close to zero under constant pressure conditions.
In the atmosphere latent heat is a property of water vapour. When water vapour condenses it releases latent heat, and latent heat must be supplied to evaporate liquid water. This heat affects the behaviour of the weather. Similar effects occur in the change from liquid water to ice and vice versa.
Yes, that's right.What you are referring to is called the enthalpy of fusion or the latent heat of fusion.
Atmospheric pressure is the force exerted by the weight of the air in the atmosphere, while water pressure is the force exerted by the weight of water in a body of water. Atmospheric pressure decreases with altitude, while water pressure increases with depth. Atmospheric pressure is measured in units like atm or pascals, while water pressure is typically measured in units like pounds per square inch (psi) or pascals.
The total pressure of water is calculated by adding the atmospheric pressure to the pressure due to the depth of the water column using the formula: total pressure = atmospheric pressure + (density of water × acceleration due to gravity × depth of water).
The saturation temperature of water at standard atmospheric pressure is 100 degrees Celsius.
