Which statement best describes liquid water and water vapor at equilibrium?
A. Liquid water stops entering the gas phase.
O B. The concentration of liquid water equals the concentration of
water vapor.
C. The concentrations of liquid water and water vapor are stable.
D. The concentration of liquid water is zero.

Respuesta :

C. The concentrations of liquid water and water vapor are stable. it describes the fact that liquid water and water vapor are at equilibrium.

Equilibrium

  • An equilibrium is achieved when no more water vapor can enter into the gas phase from the liquid water during evaporation process.
  • This happens when a saturation is attained between liquid water and the vapor phase.

Hence, option (c) is correct. The concentration of liquid water and water vapor will become stable.
