One warm spring day you and some friends go to the beach at a nearby lake. You are tossing a soft, almost fully inflated beach ball around when someone accidentally knocks it into the lake. Although it is a warm day, the water is still very cold so nobody wants to retrieve the ball. You notice that the ball seems to have deflated somewhat after sitting in the water for a while. The contact with the cool water has caused the temperature of the air inside the ball to drop, resulting in
A. a decrease in the pressure inside the ball.
B. an increase in the density of the air inside the ball.
C. a decrease in the density of the air inside the ball.
D. an increase in the pressure inside the ball.
