Energy is given off when cooling from a liquid to a solid. How much depends on the elements involved and the amount.

How does the energy required to sublime a substance compare to the energy required to melt the substance?
The energy required to sublime (solid to gas) a substance at 1 ATM pressure is greater than the energy required to melt (solid to liquid) a substance. When you compare the energies in varying pressures, however, this trend is not always the case. If you Google any 'general phase diagram', you can see that under the triple point, when all phases are in equilibrium, have solid and gas meeting under a certain pressure. In a vacuum, it would require less energy to sublime than to melt.
What is the scientific meaning for melt?
The scientific meaning for melt is when, a solid is turned into a liquid by melting the solid.
To change from solid to liquid because of the heat?
melt
How are liquid gold and solid gold alike?
they are both gold even though solid gold is solid you can melt it down into liquid.
What happens as you start to add heat to a solid substance?
The solid starts to warm up and when its temperature reaches its melting point, it will melt into a liquid or in some cases it will go directly to gas form (this process is called sublimation.)
What does the latent heat of fusion represent?
The energy required to melt a substance. (Apex)
What is the energy required to melt a solid into a liquid called?
Heat of fusion.
How do you turn a liquid into a solid?
You freeze the substance! (You remove energy from the system.)

What is latent heat of sublimation?
When a substance is below the triple point, the equilibrium will be between solid and vapor rather than solid/liquid or liquid/vapor. Sublimation is the direct change from solid to vapor without any intermediate phase change. The latent heat of sublimation is the energy required to change a given quantity of solid into the vapor at equilibrium. It is analogous to (but not the same as) latent heat of melting (energy required to melt the solid to liquid) and latent heat of vaporization (energy required to change a liquid into a gas).
What is the energy required to melt a solid at its melting point?
heat of fusion
Why does it take more heat to boil a substance than to melt it?
The energy required to completely separate the molecules in a liquid and convert them to a gas (boiling), is greater than the energy needed to completely separate the molecules in a solid and convert them to a liquid (melting).
What is the latent heat of sublimation?
No. Latent heat of vaporization is defined as the energy required to VAPORIZE 1 kilogram of a liquid completely at its boiling point. Latent heat of sublimation is the energy required to SUBLIME 1 kilogram of a solid completely into a gas at constant temperature. They're different. Note that the temperatures should be constant during the processes.
Why is heat energy needed to melt a solid. What is this heat energy called?
the energy that goes into changing a substance from a solid to a liquid (melting) is called the latent heat of fusion.
What is the latent heat of fusion?
The amount of energy it takes to boil a substance
How does the thermal energy of solid water change as its melts?
The thermal energy of the water increases as it melts, changing from a solid (ice) to liquid water. For a solid to melt, it is necessary for it to absorb energy from its surroundings.
How the thermal energy of solid water change as it melts?
The thermal energy of the water increases as it melts, changing from a solid (ice) to liquid water. For a solid to melt, it is necessary for it to absorb energy from its surroundings.
