Observe the solubility graphs for gaseous solutes. The graph on the left shows how the solubility of a gaseous solute is affected by changes in pressure. The graph on the right shows how the solubility of a gaseous solute is affected by changes in temperature.

According to the graphs, a gas becomes more soluble (solubility increases) in a liquid when
A.
both temperature and pressure are increased
B.
both temperature and pressure are decreased
C.
the temperature is increased and the pressure is decreased
D.
the temperature is decreased and the pressure is increased

A. both temperature and pressure are increased
