Answer
A tennis ball has higher air pressure in the summer than in the winter because the air pressure inside the ball is greater in the summer than the winter. The air pressure is directly proportional to the temperature inside the ball. As average temperature is higher in summer than in winter, the air pressure will be higher in the summer. As a result, the higher the air pressure, the higher the ball will bounce.
