What is added to change a solid to a liquid?
Heat is added to a solid to make a liquid... this is called melting. some additional liquid (water,ethanol,acid…) also change solid into a liquid.
Do substances absorb or release heat energy as then change from a liquid to the solid phase?
When a substance changes from a liquid to a solid it releases energy. (You take the heat out)
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.
When heat is added to or removed from a substance it may change its state. What state will most likely result if heat is added to a liquid?
In that case, the liquid may eventually change to a gas.
The amount of heat necessary to change a liquid to a solid at constant temperature?
None - heat is evolved, not required.

What is added to ice to make it change from a solid to a liquid?
heat
How does evaporation change from a liquid to a solid?
It doesn't. Evaporation is the change of state from a liquid to a gas, caused by added surface heat. You're thinking of freezing, caused by loss of heat.
How do chemicals change material?
Chemicals chAnge their state or form when energy is added ie heaT OR COLD CHANGE TO SOLID LIQUID OR GAS
What is added to solid gold to turn it into a liquid?
heat
What is the relationship between energy and phase changes?
Adding or removing energy in the form of heat causes the phase change. The amount of heat to be added or removed is called latent heat. It changes the state of a substance without changing it's temperature. There are two types of latent heat. The latent heat of fusion, and the latent heat of vaporization. The latent heat of fusion must be added to change phase from solid to liquid, and removed to change from liquid to solid. The first change is endothermic and the second change is exothermic. The latent heat of vaporization must be added to change phase from liquid to vapor, and removed to change from vapor to liquid. Again the first change is endothermic and the second change is exothermic.
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.
Do you need to increase or decrease the amount of heat energy to change a solid to a liquid?
Thermal (heat) energy must be added or removed in order to cause a change of state.
Is there a release or absorption at heat in phase change?
It depends on the phase change. When going from solid to liquid (melting), liquid to gas (boiling), or solid to gas (sublimation) heat is absorbed. When going from gas to liquid (condensation), liquid to solid (freezing), and gas to solid (deposition) heat is released.
Can you turn a liquid into a solid by freezing it?
No, freezing changes a liquid to a solid. To change a solid to a liquid you need to apply heat. The change begins when the solid reaches its melting point.
What is the amount of heat to change liquid into solid at constant temperature?
To change a liquid into solid at constant temperature, an amount of heat is released equal to the latent heat of that liquid. For water it is about 80 calories per gram.
When you heat liquid and it change phase it become a?
When you heat a liquid and it changes phase it becomes a solid.
