Latent heat- the amount of heat required by a system/ substance to change phase. It's also heat absorbed or radiated during a change of phase at a constant temperature and pressure.

What does the heat latent heat of vaporization measure?
The energy required to boil a substance
What is the energy released when steam condenses to water?
Latent heat of condensation.
What is the relation between the kinetic energy and latent heat?
None at all
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 SI unit of latent heat of fusion?
The latent heat of fusion is defined as the heat energy required to convert a kg of a substance of liquid into solid of the same substance without a change of temperature. Q = mL where Q = Heat Energy in joules, m=mass of substance, L= Latent heat of fusion Taking units, [J] = [kg] [L] [L] = [J]/[kg] so units of latent heat of fusion are joules.kg-1
Latent heat energy levels?
The latent heat energy levels refers to the heat absorbed during a change phase at a constant pressure and temperature.
The form of energy related to the change of the state of water?
The energy which must be transferred to or from a sample of water in order to change it's state is called the Latent Energy or Latent Heat - for example Latent Heat of Evaporation or Latent Heat of Freezing.
How do you define latent heat and What is its relationship to potential energy?
Latent heat is the heat required to achieve a change of phase - for example, to melt ice and convert it to water. As to the relationship with potential energy, latent heat IS a type of potential energy.
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.
What information does the latent heat of fusion give?
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.
Latent heat is the energy required for 1 kg of a substance to change?
Latent heat is the energy required for 1 kg of a substance to change ___________. phase
Why is heat energy needed to melt a solid what is this heat energy called?
This energy is the enthalpy of fusion (or latent heat of fusion).
What heat energy in the suction vapor entering the compressor is?
latent heat
Why is latent heat considered potential energy?
This is referred to as conservation of energy
What is the energy to make a phase change?
latent heat
What information does the latent of fusion give?
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.
Latent heat in terms of molecular behaviour?
The energy supplied during latent heat is used to break/weaken intermolecular bonds and NOT to increase the kinetic energy of the molecules.
