• When ice melts to form water vapor

• When water vapor cools down to form liquid water

• When a solid turns directly to a gas without turning into liquid

What is the definition and explanation of melting?

• When something that is a solid becomes a liquid by adding cold

• When something that is solid becomes a liquid by adding heat

• When something that is liquid becomes a gas by adding heat

What is the definition of freezing?

• When the solid form of matter is cooled enough and changes to a gas

• When the liquid form of matter is cooled enough and changes to a solid

• When the soild form of matter changes directly to a gas
