How does temperature effect how high a tennis ball will bounce?

Well, darling, temperature affects the bounce of a tennis ball because it changes the air pressure inside the ball. When it's hot, the air molecules inside the ball move faster, increasing the pressure and making the ball bounce higher. When it's cold, those molecules slow down, decreasing the pressure and causing the ball to bounce lower. So, next time you're playing tennis in extreme weather, just remember: temperature can be a real game-changer for your balls.
