Question
A liquid is in equilibrium with its vapour at it′s boiling point. On the average, the molecules in the two phases have equal :
Options
A.inter- molecular forces
B.potrntial energy
C.kinetic energy
D.totalenergy
Solution
In, liquid ⇋ vapour equilibrium, yhe rate at which molecules escape from the liquid surface to gaseous phase equals the rate at which molecules in the gas phase strikes the surface and become the part of liquid. Hence the molecules in the two phases have kinetic energy.
