Rubber can degrade when exposed to high levels of radiation, causing it to become brittle and lose its elasticity. Convection can lead to changes in rubber properties due to temperature fluctuations, but it generally does not have a significant impact. Conduction can affect rubber by transferring heat and potentially altering its mechanical properties, depending on the temperature conditions.

What are the different types of heat transfer?
There are three types of heat transfer, namely conduction, convection and radiation. Heat is transferred until the reach a state of equilibrium. Conduction is basically the transfer of heat through a surface of contact, such as a fire to the base of a pot. We say that a material is a good or poor conductor of heat when heat travels quickly or slowly in that particular material. Good conductors of heat are metals whereas poor conductors of heat are rubber and Styrofoam. Conduction cannot occur in a vacuum. Convection is the transfer of heat through molecules. It can only occur in liquids and gases as there are relatively big spaces between the molecules. A convection current is where hot air rises and cold air sinks. Convection cannot occur in a vacuum. Radiation is the transfer of heat through a vacuum. Heat is transferred from the Sun to Earth through radiation.
What can't heat pass through?
Heat cannot pass through a vacuum because it requires a medium such as air or water to transfer thermal energy. Additionally, materials like insulators, such as wood, plastic, and rubber, are poor conductors of heat and can limit the transfer of thermal energy.
Is it true that heat is an example of insulator?
No, heat is not an example of an insulator. Insulators are materials that do not conduct heat well, such as wood or plastic. Heat is a form of energy that can be transferred through conduction, convection, or radiation.
Is the stretchiness of a rubber band affected by the temperature?
Yes, the stretchiness of a rubber band is affected by temperature. When exposed to higher temperatures, rubber bands become more stretchy and flexible, while colder temperatures can cause the rubber to become stiffer and less stretchy.
Why is a rubber band an insulator?
The electron configuration of rubber (natural of artificial is such that there is a big gap between valance band and conduction band of electrons. Electrons has to make a transition from valence band to conduction band in order to conduct electricity.

How does a vacuum flask keep its energy?
1. Silvered interior reflects any heat which may transfer though radiation 2. Moderately hard vacuum almost eliminates transfer by conduction (& convection though this would be modest anyway) 3. Vacuum bottle is only supported by a few small rubber pads - again limiting conduction 4. Cap designed with air gaps to reduce conduction: plastic/air/plastic/air/plastic 5. Most flasks have an outer of plastic which is a reasonable insulator against conduction heat loss. The vacuum itself is the most significant design point.

What makes rubber such a bad conductor for electricity?
'Cause the conduction band of rubber are far away from each other.
Is rubber affected by different temperature?
no
Why is rubber a good electrical insulator?
The electron configuration of rubber (natural of artificial is such that there is a big gap between valance band and conduction band of electrons. Electrons has to make a transition from valence band to conduction band in order to conduct electricity.
Is the rubber inside of a tennis ball affected by weather?
yes the weather effect the rubber inside

What kind of insulator would stop conduction?
A material that is a good insulator, such as rubber, plastic, or glass, would stop conduction of electricity. These materials have high resistance to the flow of electrons, preventing electrical currents from passing through them.
How do you defrost a chicken in a microwave convection?
Neither you leave it out in a semi cold enviorment. if you put it in the micro wave you chicken will turn to rubber. If you put it in the convection oven it will cook the outside and the inside will still be raw.
