Answer:
When the rubber band is stretched its molecules get straightened. This means a decrease in volume. This causes its temperature to increase just like an ideal gas, which heats up when it is compressed. If you then let it cool down while stretched and release it, it will get colder than room temperature. This is because its volume has increased, so the temperature drops - just like an ideal gas.
As the rubber is stretched the bonds between adjacent chains are broken. These bonds are relatively weak compared with the bonds along each chain molecule.
You can observe another very odd effect. Stretching a rubber band makes it get hot – heat energy is lost. Therefore if you put heat energy into a rubber band it will get shorter – unlike most materials when they are heated.
Hope this helps.

Stretching a rubber band makes it get hot – heat energy is lost.You input potential (stored) energy into the rubber band system when you stretched the rubber band back. Because it is an elastic system, this kind of potential energy is specifically called elastic potential energy. The farther you pull a rubber band back, the further it will fly. Unless the rubber band is pulled far.
