Im doing this coursework about what material can keep heat the longest. My test results show that Polystyrene was the best material, but why ? Why is polystyre a good insulator?

http://www.eere.energy.gov/consumerinfo/refbriefs/ed3.htmlbtw do you know what the gas in plastic foam is? is it nitrogen or air or carbondioxide or what? maybe someone here knows, I dont.
Polystyrene is a good insulator because it is made up of tiny air pockets that slow down the transfer of heat and electricity. This makes it difficult for heat or electricity to pass through, keeping the desired temperature or preventing the flow of electricity.
Polystyrene prevents heat transfer through conduction, convection, and radiation. The tiny air pockets in polystyrene act as barriers that reduce the movement of heat energy between objects, preventing heat transfer.
Yes, polystyrene is a good insulator for both hot and cold temperatures. It has a low thermal conductivity, meaning it does not conduct heat well. This makes it effective in both preventing heat from escaping and preventing heat from entering.
Polystyrene is a better insulator than other materials because it has a high R-value, which measures the material's resistance to heat flow. Polystyrene has a higher R-value compared to other commonly used insulating materials, making it more effective in preventing heat transfer.
Polystyrene is not considered environmentally friendly as an insulating material. It is a non-biodegradable plastic and can release toxic chemicals when burned. However, there are now more eco-friendly options available, such as polystyrene made from recycled materials or biodegradable alternatives like hemp insulation.
