It's the latent heat of fusion.
It varies between substances, for water, it's around 333 joules of energy per gram of water, about 80 calories per gram in the old money.

What is the name given to heat energy at melting point?
The heat energy required to change a substance between solid & liquid at constant temperature is called the "latent heat of fusion". If the change is from solid to liquid the substance gains this energy. If the change is from liquid to solid the substance gives up this energy. The exact amount of latent heat of fusion is different for different substances.
What is the amount of energy needed to raise the temperature of 1 kg of a substance 1C.?
A substance's molar specific heat capacity is the amount of energy required to raise one mole of that substance 1 degree Celsius.For water, this is exactly one calorie, assuming the state of the water does not change. Otherwise, it depends on the substance, and the substance's current temperature and state.for apex its latent
What is substances specific heat?
The amount of heat required to increase the temperature of the substance to 1 degree greater than that of the initial temperature of the body!
A change of state in which energy is removed from a substance is called an?
A change of state where energy is removed from a substance is called an exothermic reaction. This chemical reaction releases energy in the form of light or heat.
What is the average amount of energy of motion of each particle in a substance?
The average amount of energy of motion (also known as kinetic energy) in the particles of a substance (atoms and molecules) is measured by the temperature of that substance. More energy will produce a higher temperature.
What is specific latent heat.?
It is the amount of energy required to change the state of 1kg of a substance with no change in temperature.
What is specific heat a measure of?
The amount of energy it takes to change the temperature of a substance by a certain amount. How much energy it takes to heat a substance ~APEX
What is specific heat capacity?
Is the amount of energy that is required to change the temperature of 1kg of a substance by 1 degree Celsius with no state change.
What is a latent heat energy levels?
Latent heat- the amount of heat required by a system/ substance to change phase. It's also heat absorbed or radiated during a change of phase at a constant temperature and pressure.
What is the energy required to go from liquid to gas called?
The latent heat of vaporization
What is the latent heat of fusion?
The amount of energy it takes to boil a substance
What change when the amount of a substance change?
total thermal energy

Latent heat is the energy required for 1 kg of a substance to change?
Latent heat is the energy required for 1 kg of a substance to change ___________. phase
What does the latent heat of fusion represent?
The energy required to melt a substance. (Apex)
How does temperature relate to amount of energy present in a substance?
Higher temperature means greater energy content compared to a lower temperature. The energy required to change the temperature is proportional to the mass of the system, the specific heat capacity, and the temperature change.
How does a substance gain heat?
A substance gains heat, or otherwise known as thermal energy, in many different ways. These can be from pressure, friction, the transformation of chemical energy to thermal energy, the transformation of electromagnetic energy to thermal energy, potential energy to the energy of motion (kinetic energy) or a substance can become exothermic during, and after a chemical change if the amount of energy produced from the broken bonds is greater than the amount of energy required for rearranged bonds to be made.
