as water condenses the temperature increases
Key Concepts. 1  Condensation is the process in which molecules of a gas slow down, come together, and form a liquid. 2  When gas molecules transfer their energy to something cooler, they slow down and their attractions cause them to bond to become a liquid. 3  Making water vapor colder increases the rate of condensation.ut as the concentration of water molecules increases in the container, the rate of condensation increases. Eventually, the rate of condensation equals the rate of evaporation and the water molecules go back and forth between the liquid and the gas.
