The reason why the ball moves faster is that when the ball hits the wall it causes friction and the molecules move faster an hit the wall harder therefore hotter molecules move faster and cold molecules move slower. When the ball is cold there is low internal pressure and when the ball is hot there is high internal pressure which makes the ball bounce better, it also makes it bigger. More energy is absorbed when the ball is hot; the ball also expands when it gets hotter. A ball bounces better if...
