For a cloud to form, the air must have these 2 things: (choose 2)

Why don’t we see all gases condense into liquids when the temperature outside drops?

• Some locations on Earth do not have temperatures needed for a substance to reach its melting point.

• Some gases will only condense at temperatures colder than temperatures on Earth

• All gases have the same freezing point.

• The boiling point of a gas depends on the freezing point.
