Lab partners are designing an experiment that shows the important steps of the water cycle. For their experimental design, which of the following procedures could best be used to demonstrate the difference between condensation and evaporation?

• To show condensation- increase the temperature within the cycle; to show evaporation-decrease the temperature

• To show condensation- decrease the temperature within the cycle; to show evaporation- increase the temperature

• To show condensation- maintain a constant temperature within the cycle; to show evaporation- increase the temperature

• To show condensation- maintain a constant temperature within the cycle; to show evaporation-decrease the temperature
