Temperature does not affect the bounce of a rubber ball. Let's say you bounce a rubber ball on the grass. The result will be different then bouncing a rubber ball on a concrete surface. The result is different because you are using a solid, hard surface to bounce the ball with. But the temperature will not affect the bounce of a rubber ball. you can test it out for youself.
First, consider that a bouncing ball is an elastic system, that is, it deforms and returns to its original shape. The process of returning to its original shape is responsible for the bounce, the faster it returns, the higher it bounces. For most solids, including a rubber ball, higher temperatures make it more plastic, or more easily deformed and less able to recover its original shape, therefore higher temperatures (hotter) will make the ball bounce less. Lower temperatures will make the solid more brittle or elastic, and make the ball bounce higher. These observations, however, are based on the assumption that the ball is solid and of uniform composition throughout. If the ball is hollow, the situation is much different. Within normal living conditions temperatures (about 10 degrees F to about 110 degrees F) the air inside the ball has a greater effect on bouncing. Low temperatures cause the air to become denser, thus reducing both volume and pressure inside the ball. This makes the ball partly deflate and when it is bounced, it deforms horizontally with little or no recovery, losing its bounce. At the higher temperatures, the air expands, increasing the pressure, thus the tension on the ball is greater and the bounce is significantly higher.
Let me also point out that the surface upon which the ball is bounced influences the system as well. A steel ball or glass ball represents some of the more elastic systems we know, and they will bounce very high on a solid surface with enough mass to resist the force of the ball. If you drop a glass marble on a marble countertop, it will bounce very high. Dropping the marble on a carpeted floor, however, results in the marble just lying there. Again, the function is elasticity, even to the point of being brittle, that creates the ability to return to form and bounce. A rubber ball, being plastic in nature and easily stretched and deformed, depends on its lesser mass and will bounce from a less-than-optimum surface for impact recovery.
Yes, temperature affects rubber. If you freeze rubber, it will become stiff, and if you heat it, it will soften and become more flexible.
it makes it not bounce as high
temperature does affect the bounce of a ball!
yes
Neither. When a rubber ball gets hot, the rubber begins to lose its elasticity. It doesn't bounce as high. When a rubber ball gets really cold, it starts to behave rather like a rock. It hardly bounces at all The temperature of highest bounce depends on exactly what the ball is made of, but it is probably not all that far from room temperature.
A glass ball will bounce higher than a rubber one.

When the ball is at a low temperature, the molecules are not flexible and bounce only to a small height. On the other hand, if the ball is warm or at a higher temperature, it will bounce longer heights.
Temperature does affect the bounce of a ball. I know this because I did an expiremnt on the exact same question. The hotter the temperature is, the more pressure builds up inside a ball and the more bouncier it will be. The colder it is, pressure decreaces making it bounce lower than what the ball bounced at room temperature. In conclusion, the ball bounces higher when it is warmer and it bounces lower when it is colder.
There is no doubt any rubber ball will have an optimum "bounce" temperature and it is unlikely this is room temperature. it could in fact be cooler. It is well known squash balls are warmed up before being used, so it is likely warming bouncy balls up will make them bounce more.
Yes. This is because in the center of a golf ball there is either a rubber or a liquid core. This means that when the rubber or liquid is heated, it is easier to move around. When the rubber or liquid becomes colder, the core becomes harder, thus making it harder to bounce.
The leather is put on the basketball for grip, wear and tear, and consistency. The bounce of the ball comes from the rubber bladder that the leather is surrounding. Air pressure and the quality of the ball effect it's bounce more than the leather.
