What is the melting point?

• The temperature at which a substance changes from its solid phase to its liquid phase

• The temperature at which a substance changes from its liquid phase to its gas phase

• The temperature at which a substance changes from its gas phase to its liquid phase

• The temperature at which a substance changes from its liquid phase to its solid phase

What is a solution?

• A mixture in which solute particles do not settle
