Nuclear fusion releases energy in what form?
Nuclear fusion releases energy in the form of heat and light. This occurs when the nuclei of two atoms combine to form a new, heavier nucleus, releasing a large amount of energy in the process.
What is the substance that absorbs and releases heat in a cooling system?
The substance that absorbs and releases heat in a cooling system is called the refrigerant. When the refrigerant absorbs heat from the surroundings, it evaporates and carries the heat away. When the refrigerant releases the heat, it condenses back into a liquid state, ready to absorb heat again.
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.
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?
The energy required to melt a substance
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.
