Physics 2010 JAMB Past Questions - Question 21: A vapour is said to be saturated when

Correct Answer

D

Explanation

A vapor is said to be saturated when it is in equilibrium with its liquid phase at a given temperature and pressure. In other words, a saturated vapor is a vapor (or gas) that contains the maximum amount of vaporizable substance (usually a liquid) it can hold at a particular temperature and pressure without condensing into a liquid. When a vapor is saturated, any additional increase in temperature or pressure would cause it to either condense into a liquid or become superheated, depending on the specific conditions.

Saturated vapor is a concept commonly used in the study of phase diagrams, thermodynamics, and in engineering applications, especially in the design of refrigeration and steam systems. The point at which a vapor becomes saturated depends on the substance and its phase diagram, as well as the surrounding conditions of temperature and pressure.
