Which law suggests that at a constant pressure, the volume of gas is directly proportional to its temperature?

The law that suggests that at a constant pressure and the volume of gas directly proportional to its temperature is the Boyle's law.

Explanation:

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.
