Question 28
Simon wanted to show how seawater helps contribute to water vapor in the
water cycle. He filled a beaker with 200 ml of seawater at room temperature
and heated the seawater to speed up evaporation. He then cooled the hot
water vapor and allowed the water droplets formed to flow back into the
beaker. He put the set-up in a closed glass tank to represent the water cycle.
The graph below shows the temperature of the water in the beaker.
During which period will most of the water vapor be formed?
A. AB
B. BC
C. CD
D. AC
