Air is the best insulator among the options listed. It has low thermal conductivity, meaning it does not easily transfer heat. Thermocol, cotton, and aluminium are not as effective as insulators compared to air.
Air is the best insulator among silver, copper, iron, and air. This is because air has a lower thermal conductivity compared to the metals silver, copper, and iron. Insulators with low thermal conductivity are better at reducing heat transfer.
Air is the best insulator of the three substances mentioned (air, glass, and silver) because it is a poor conductor of heat and electricity. Glass is better than silver at insulating heat due to its higher resistance to heat transfer, but both air and glass have better insulating properties than silver. Silver is a good conductor of heat and electricity, making it a poor insulator compared to air and glass.
It is not recommended to mix air and hydrogen in a tire. Using hydrogen in tires can be dangerous due to its flammability and potential for explosion. It is best to use the appropriate type of compressed air for inflating tires.
