Question

Consider a closed flask containing a liquid and its vapor. Which statement is incorrect?
A.) The vapor exerts a pressure called the vapor pressure
B.) Increasing the temperature of the liquid would lead to a great vapor pressure
C.) Evaporation and condensation will eventually cease after a constant pressure has been attained
D.) Increasing the volume of the container at a constant temperature would cause increased condensation until the pressure of the vapor was once eagain the same as it had been

Answer 1

Answer:

C). Evaporation and condensation will eventually cease after a constant pressure has been attained

Explanation:

A) The vapor exerts a pressure called the vapor pressure is correct statement B) On increasing the temperature more vapor will be formed as thus leading to a higher vapor pressure.

C) This is an incorrect statement,  Evaporation and condensation never stops what ever may be the pressure. Although they may achieve an equilibrium that is the rate of evaporation may be equal to the rate of condensation.

d) This is again a correct statement as vapor pressure is an extrinsic property that it depends upon the volume or mass of liquid. Greater the volume greater will be the vapor pressure.
