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.
What else can I help you with?
Draw and discuss the relationship of heat of fusion and heat of vaporization?
The heat of fusion is the energy required to change a substance from solid to liquid at its melting point, while the heat of vaporization is the energy required to change a substance from liquid to gas at its boiling point. Both values are specific to each substance and represent the amount of energy needed to break intermolecular forces during phase changes, with vaporization requiring more energy than fusion due to the additional change in state.
What is the relation of the molar heat of fusion to the molar 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).
What is it called when heat energy required to break up the attraction of liquid molecules?
When liquid molecules absorb enough heat energy, evaporation occurs.
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 specific heat is the energy used to evaporate water or melt snow?
The specific heat of water is the amount of energy required to raise the temperature of water by 1 degree Celsius. The heat of vaporization is the energy required to change water from a liquid to a gas (steam) at its boiling point. The heat of fusion is the energy required to change water from a solid to a liquid (melt snow) at its melting point.
The amount of energy needed to change a material from a solid to a liquid is the heat of what?
The latent heat of evaporation
The molar heats of sublimation and fusion of iodine are 62.3kjmol and 15.3kjmol respectively calculate the molar heat of vaporization of liquid iodide?
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.

What is it called when heat energy required to break up the attraction of liquid molecules?

What is the difference between heat of fusion and heat of vaporization?
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.
What is the difference between the heat of fusion and the heat of vaporization in terms of their effects on phase changes?
The heat of fusion is the energy required to change a substance from a solid to a liquid, while the heat of vaporization is the energy needed to change a substance from a liquid to a gas. Both are types of phase changes that require specific amounts of energy to occur.
What is enthalpy of fusion vaporization?
The enthalpy of fusion is the heat energy absorbed or released when a substance changes from solid to liquid at its melting point. The enthalpy of vaporization is the heat energy absorbed or released when a substance changes from liquid to gas at its boiling point.
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 scientific name for ice forming and melting?
For forming it is Heat of (Fusion) and for melting its Heat of (Vaporization).
What is the difference between the heat of vaporization and the heat of fusion in terms of their effects on phase changes?
The heat of vaporization is the energy required to change a substance from a liquid to a gas, while the heat of fusion is the energy needed to change a substance from a solid to a liquid. Both play a role in phase changes by providing the necessary energy to break intermolecular forces and transition between states of matter.
How much heat is necessary to vaporize 500 grams of ice at its freezing point?
The heat required to vaporize 500 grams of ice at its freezing point is the sum of the heat required to raise the temperature of the ice to its melting point, the heat of fusion to melt the ice, the heat required to raise the temperature of water to its boiling point, and finally the heat of vaporization to vaporize the water. The specific heat capacity of ice, heat of fusion of ice, specific heat capacity of water, and heat of vaporization of water are all needed to perform the calculations.
