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 else can I help you with?
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 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.
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 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.
What is the relationship between the heat of vaporization and boiling point of a substance?
The heat of vaporization is the amount of energy needed to change a substance from a liquid to a gas at its boiling point. The higher the heat of vaporization, the higher the boiling point of the substance.
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

What is greater water heat of fusion or its heat of vaporization?
The heat of vaporization of water is greater than its heat of fusion. Specifically, the heat of vaporization is approximately 2260 joules per gram, while the heat of fusion is about 334 joules per gram. This means that it requires significantly more energy to convert water from a liquid to a gas than to change it from solid to liquid.
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.
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 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 heat fusion and heat of vaporization measures of?
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 is it called when heat energy required to break up the attraction of liquid molecules?
When liquid molecules absorb enough heat energy, evaporation occurs.
Q - What is the difference between latent heat of fusion and latent heat of solidfication?
They are the same thing. Fusion and solidification both mean the changing of a liquid to a solid.
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
