Shown here is a representation of a closed container in which you have just placed 10 L of H2O. In our experiment, we are going to call this starting point in time t = 0 and assume that all of the H2O is in the liquid phase. We have represented a few of the H2O molecules in the water as dots.
a. Consider a time t = 1, at which some time has passed but the system has not reached equilibrium.
i. How will the level of the liquid H2O compare to that at t = 0?
ii. How will the vapor pressure in the flask compare to that at t = 0?
iii. How will the number of H2O molecules in the vapor state compare to that at t = 0?
iv. How does the rate of evaporation in this system compare to the rate of condensation?
v. Draw a picture of the system at t = 1.
b. Consider a time t = 2, at which enough time has passed for the system to reach equilibrium.
i. How will the level of the liquid H2O compare to that at t = 1?
ii. How will the vapor pressure in the flask compare to that at t = 1?
iii. How will the number of H2O molecules in the vapor state compare to that at t = 1?
iv. How does the rate of evaporation in this system compare to the rate of condensation?
v. Draw a picture of the system at t = 2.
