It is the Styrofoam cup as it is not a good conductor of heat but the metal cup is a good conductor of heat.
Metal is a good conductor of heat, therefore heat leaks out of it easily, and it does not keep food hot all that well. Styrofoam keeps food hot.
Styrofoam is an excellent insulator.
If you are sipping water or any liquid from a Styrofoam cup , you might feel hurt when water touches your teeth on every sip. This will especially happen if you are walking on carpets . The reason is that charge built-up on yourbody during walking or doing any motion . This cahrge is not transferred to the liquid as Styrofoam is highly insulating . This voltage difference is sensed by the nerves inside your teeth and they hurt. To avoid this keep a metal spoon inside the cup and keep a finger on the cup or touch your spoon before each sip . It wont hurt again . - M PATHAK
Styrofoam because it has a thick layer and is a good insulator.Paper and plastic are could alternatives but Styrofoam would work better, therefore glass would be the worst one to use because it would only keep it warm for a couple of minutes.
Styrofoam is a better insulator of heat than plastic. The plastic allows the heat in and out and the cold in and out. The Styrofoam helps keep the heat in.
styrofoam, but warning fammable and unsafe for the environment!

Yes, because it does not conduct heat.

Usually food it packed in Styrofoam to keep it cold (or warm)
styrofoam cups keep you beverages hot or cold because they are awesome
