That's the amount of heat you have to add to the solid form at the melting temperature
in order to melt it to the liquid form at the same temperature.
Looking at it the other way: It's the amount of heat you have to remove from the liquid
at the freezing temperature in order to freeze it solid at the same temperature.
What else can I help you with?
The energy required to melt one gram of a substance is known as what?
The energy required to melt one gram of a substance is known as the heat of fusion.
What is the measurement of how much heat energy is required for a substance to melt?
The measurement of how much heat energy is required for a substance to melt is called the heat of fusion. It is the amount of energy required to change a substance from a solid to a liquid at its melting point.
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
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 a similarity between heat fusion and heat solidification?
When changing from a solid to a liquid, melting, the heat absorbed is called the heat of fusion. When the reverse takes place, freezing, it is called the heat of solidification. For a single substance they are the same.
The energy required to melt one gram of a substance is known as what?

What a substance does when it releases heat of fusion?
It explodes
What is the measurement of how much heat energy is required for a substance to melt?
The measurement of how much heat energy is required for a substance to melt is called the heat of fusion. It is the amount of energy required to change a substance from a solid to a liquid at its melting point.
The amount of energy involved in melting a substance without changing its temperature is called the?
It is called the enthalpy of fusion of a substance, also known as (latent) heat of fusion.
A sentence for heat of fusion?
Because of the heat of fusion the ice is now water
The amount of heat needed to melt one kilogram of a substance?
The amount of heat required to melt one kilogram of a substance is known as the heat of fusion or the latent heat of fusion. It represents the energy needed to change a solid into a liquid at its melting point without a change in temperature.
What does the latent heat of fusion?

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
When a substance goes from a solid to a liquid state without a change in temperature the heat added during the transformation is called?
That's the heat of fusion.
How does the presence of hydrogen bonds affect the heat of fusion of a substance?

What is the specific latent heat of fusion for a substance that takes 550 kJ to melt 14 kg at 262 K?
The specific latent heat of fusion can be calculated by dividing the energy required to melt the substance by the mass of the substance. In this case, the specific latent heat of fusion would be (550 kJ) / (14 kg) = 39.29 kJ/kg.
What is the lantent heat of fusion?
The latent heat of fusion is the amount of heat energy required to change a substance from a solid to a liquid at its melting point. It is a physical property specific to each substance and is measured in joules per gram (J/g).
