Question 65
Arun did an experiment using two plants in pots. Plant A was uncovered; plant B had a bag covering its leaves, while the soil was uncovered. He measured the mass of each plant and pot at the same time every day for seven days.
| Day | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
|---|---|---|---|---|---|---|---|
| A + pot / g | 945 | 925 | 901 | 877 | 855 | 832 | 808 |
| B + pot / g | 960 | 952 | 946 | 940 | 936 | 932 | 929 |
Daily mass losses for A: 20, 24, 24, 22, 23, 24 g. For B: 8, 6, 6, 4, 4, ___ g.
At the end of the experiment, Arun found little drops of water on the inside of the bag that covered plant B. Explain how they got there.
