CHEMISTRY: heating and cooling curve

the stronger the forces of attraction between particles

the higher the b.p

a graph that shows how the temperature of a substance changes on heating or on cooling

heating/cooling curve

If the temperature of the environment falls below the boiling point the substance is a

solid

f the temperature of the environment falls is between the boiling and melting point the substance is a

liquid

If the temperature of the environment is above the boiling point the substance is a

gas

a chemical substance inside a confined amount of liquid, gas,or solid which differ from the chemical composition of the material/compound

impurity
