Aliquid placed in a closed container will evaporate until equilibrium is reached.

at equilibrium, which of the statements (a-d) is false?

a)the partial pressure exerted by the vapor molecules is called the vapor pressure of the liquid.

b)liquid molecules are still evaporating.

c)the number of vapor molecules remains essentially constant.

d)the boundary (meniscus) between liquid and vapor disappears.

e)all of these are true.

(B) Liquid molecules are still evaporating.

Explanation:

Vapor Pressure is exerted by the vapor of the liquid, at equillibrium the partial pressure exerted by vapor molecules is called as vapor pressure by defition of vapor pressure the statement A is true.

Statement B , Liquid molecules are still evaporating this statement may not be true as equillibrium is reached no more liquid state molecules will pass in the vapor phase.

Since its an quillibrium the number of the moleciles in vapor and liquid phase remains constant hence the statement C is also true.

Statement D, The boundary (meniscus) between liquid and vapor disappears this statement is also true as the liquid evaporates the meniscus may fall down.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
