Question 1 Report
Vapour is said to be saturated on top of an enclosed liquid if _________
Answer Details
The correct option is "The rate of condensation is equal to that of vaporization".
When a liquid is enclosed and heated, the temperature and pressure increase causing the liquid to turn into a vapor or gas. As the vapor rises, it cools and reaches a point where the temperature and pressure are just right for the vapor to condense back into a liquid. At this point, the rate of condensation (the amount of vapor turning back into liquid) is equal to the rate of vaporization (the amount of liquid turning into vapor). This is called being "saturated".
So, when vapor is said to be saturated on top of an enclosed liquid, it means that the rate of condensation and vaporization are equal, and the amount of vapor and liquid are in balance.
