The heat of fusion is the amount of heat (not temperature) required to change a solid to a liquid. It is also known as the melting point.
The heat of vaporization is the amount of heat (not temperature) required to change a liquid to it's gaseous state. It is also know as it's boiling point.
There is no relationship between heat of fusion and heat of vapourisation
Molar heat of fusion: the heat (enthalpy, energy) needed to transform a solid in liquid (expressed in kJ/mol). Molar heat of vaporization: the heat (enthalpy, energy) needed to transform a liquid in gas (expressed in kJ/mol).
When liquid molecules absorb enough heat energy, evaporation occurs.
The first is called enthalpy of vaporization, the second is called enthalpy of fusion.
thermol
The latent heat of evaporation
There is no relationship between heat of fusion and heat of vapourisation
It is a known fact : Molar heat of sublimation = molar heat of fusion + molar heat of vaporization so, molar heat of vaporization = molar heat of sublimation - molar heat of fusion Mv = 62.3 kJ/mol - 15.3 kJ/mol Mv = 47 kJ/mol.
both the heat of fusion and the heat of vaporization
Molar heat of fusion: the heat (enthalpy, energy) needed to transform a solid in liquid (expressed in kJ/mol). Molar heat of vaporization: the heat (enthalpy, energy) needed to transform a liquid in gas (expressed in kJ/mol).
Latent heat is the amount of thermal energy required to change the phase of a substance. Latent heat of fusion is the amount of energy needed to change it from a solid to liquid or a liquid to solid, and the latent heat of vaporization is the thermal energy needed to change from a liquid to gas or a gas to liquid. For example, in the equation Q = mL, Lfusion (latent heat of fusion) for water is 75.5 cal/gram. Lvaporization (latent heat of vaporization) for water is 539 cal/gram. Substances have different latent heats.
When liquid molecules absorb enough heat energy, evaporation occurs.
The heat needed to melt one gram of a solid at its melting point is the heat of fusion.
Because the latent heat of fusion and latent heat of vaporization are very high
The scientific name for ice forming is "freezing" or "solidification." The scientific name for ice melting is "melting" or "fusion."
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.
The heat energy released when water vapor condenses to a liquid is called "heat of vaporization".
