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 heat that is released when water condenses and changes to liquid form?
The latent heat of vaporisation.
What is thermal energy of melting?
its the latent heat of fusion or simply Enthalpy of fusion.ie,this heat is absorbed or added at melting temperature.for eg latent heat of fusion of ice= 6.02 KJ/mol (80cal/gm).
Why does the temperature stops rising during melting and boiling point?
Because the latent heat of fusion and latent heat of vaporization are very high
What is the energy required to go from a solid to a liquid called?
The latent heat of fusion
Why is latent heat of vapourisation higher than latent heat of fusion?
latent heat of vapourisation is the heat energy required to change 1 kg of a liquid to gas at atmospheric pressure at its boiling point where latent heat of fusion is the amount of heat energy required to change 1 kg of solid to liquid at its melting point so that is why latent heat of vapourisation higher than latent heat of fusion.
Why the time needed to vaporize a sample is greater than the time needed to melt a sample?
The amount of time depends on the latent heat of vaporisation and the latent heat of melting.
What ingredient converts liquid to solid medium?
Temperature is the measurement of the HEAT CONTENT of an item or article. Freezing the liquid to form the solid includes the release of "the latent heat of crystallization". Melting the solid to form the liquid includes the absorption of "the latent heat of melting". From either the solid or the liquid phases, the appearance of a gas includes absorption of "the latent heat of Vaporization".
What is the definition of melting?
Melting is when a solid becomes hot and "melts" into a liquid. (wax)
What process releases the latent heat of water vapor to make the air warmer?
1. Process that release "Latent Heat" : a. Freezing, b. Condensation, - (Greatest amount of released Latent Heat.) c. Deposition. 2. Process that absorbs "Latent Heat" : a. Melting, b. Evaporation, - (Greatest amount of absorbed Latent Heat.) c. sublimation.
What happens when water at its melting point solidifies to ice without any change in temperature?
Latent heat is emitted.
What is the energy required to go from solid to a liquid called?
The latent heat of fusion
Why is heat energy needed to melt a solid. What is this heat energy called?
the energy that goes into changing a substance from a solid to a liquid (melting) is called the latent heat of fusion.
