What does this graph tell you about the relationship between temperature and the amount of water vapor that air can hold?

As the temperature increases so does the amount of moisture that the air can hold.

Explanation:

The graph shows that at 0 degrees C air can hold about 5 g/m cubed while at 20 it can hold 19 g/m cubed meaning that the amount of moisture increases as temperature increases.
