This change in the state of matter (liquid to solid) is called freezing.
This change in the state of matter (solid to liquid) is called melting.
They are physical change, the chemical nature of the molecules is not changed.

What is the temperature called at which a substance changes from a solid to a liquid?
It is the melting point of the substance.
Does it gain or lose energy when a solid melts?
anytime a substance changes it's molecular structure (solid to liquid, liquid to solid, liquid to gas, solid to gas, gas to liquid) it loses engergy.
Does a liquid turn into gas when the particles get colder?
No, a substance changes from gas to liquid to solid as it cools.
How do you describe each phase change?
Endothermic phase changes - the substance is gaining energy (being heated) and the molecules are getting more active.- solid to liquid: melting- liquid to gas: vaporization- solid to gas: sublimationExothermic phase changes - the substance is losing energy (cooling) and the molecules are slowing down.- gas to liquid: condensation- liquid to solid: freezing- gas to solid: depositionMemory helper: exo is like exit, and the heat energy exits the substance during an exothermic phase change.
By removing heat what happesn 1. a liquid changes to a solid. 2 a solid changes to a liquid. 3 a liquid changes to a gas. 4. a solid changes to gas?
1. a liquid changes to a solid. This process is called freezing, and involves the loss of heat.
What happens to a substance during changing between a solid to a liquid?
When a substance changes from a solid to a liquid and vice versa, its density changes.
What happens at the melting of a substance?

What happens to the temperature of a substance as it changes from a solid to a liquid?
it heats up
What happens to heat energy when a substance changes from solid to liquid?
it melts
What happens when substances goes through a phase change?
Melting: the substance changes back from the solid to the liquid. Condensation: the substance changes from a gas to a liquid. Vaporization: the substance changes from a liquid to a gas. Sublimation: the substance changes directly from a solid to a gas without going through the liquid phase.
When a substance changes from a liquid to solid it is...?
When a substance changes from liquid to solid is called freezing.

What is the point at which a substance changes from a solid to a liquid?
A substance changes from a solid to a liquid at its melting point
What happens when a substance changes from a solid to a gas without becoming a liquid?
It sublimes
