Rubber can generate heat through friction when undergoing mechanical stress, such as bending, stretching, or rubbing. This phenomenon is known as hysteresis heating, where energy is lost as heat due to the internal friction within the material.

No, rubber is not a good conductor of heat. It is a poor conductor of heat because it is a good insulator, meaning it does not allow heat to pass through it easily. This property makes rubber useful for applications where heat insulation is required.
Exposure to heat can cause a rubber band to lose its elasticity and become brittle. The heat breaks down the molecular structure of the rubber, leading to a loss of flexibility and strength in the rubber band. Over time, this can cause the rubber band to crack or snap more easily.
When heat is added to a rubber band, the rubber band will expand and become more flexible. This is because the heat causes the rubber molecules to move around more freely, allowing the rubber band to stretch more easily.
Rubber has insulating properties, so it can help to keep heat out to some extent. However, its effectiveness will depend on the thickness and composition of the rubber material. Generally, rubber alone may not provide as much insulation as other materials designed specifically for heat resistance.
Rubber minimizes heat transfer due to its low thermal conductivity, meaning it does not readily conduct heat. This property can help insulate and maintain consistent temperatures in various applications such as seals, gaskets, and tires. Rubber can also absorb and dissipate heat efficiently, reducing heat transfer.
