Test: Vapours, Saturated Vapour Pressure, and Atmospheric Phenomena - JAMB MCQ

Saturated vapours have a higher temperature.

Saturated vapours contain a higher concentration of molecules.

Saturated vapours can exist in equilibrium with the liquid phase.

Saturated vapours can only be produced at high pressures.

Higher S.V.P corresponds to a lower boiling point.

Higher S.V.P corresponds to a higher boiling point.

S.V.P and boiling point are independent of each other.

S.V.P and boiling point have an inverse relationship.
