cooling curve

the substance is not cooled evenly

the substance is hard

the substance has a low melting point than the room temperature

the substance has a high melting point

Liquid particles absorb heat and turn into solid

Gas molecules contain more kinetic energy than liquid molecules

Solid has lower force of attraction between molecules than liquid

The process to turn liquid to gas is condensation

decreasing the temperature

increasing the temperature
