It is the Styrofoam cup as it is not a good conductor of heat but the metal cup is a good conductor of heat.
A styrofoam cup can help to retain heat, but it is not as effective as materials like ceramic or insulated metal. Hot water in a styrofoam cup will cool down faster compared to using a better insulated material.
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.
Metal containers can help keep food hot by retaining heat better than other materials. Insulated metal containers, such as thermoses, are designed specifically to retain heat for longer periods of time. However, the effectiveness of a metal container in keeping food hot will also depend on factors like the type of metal, the insulation, and the initial temperature of the food.
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 can keep a drink cold for several hours, depending on the surrounding temperature and insulation quality. It is more effective at blocking heat transfer than maintaining a specific temperature, so the duration can vary.

styrofoam, but warning fammable and unsafe for the environment!
thermos cup
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
Styrofoam
it can what is wired
Styrofoam is used to keep drinks cold or warm.
An anchor is a heavy piece of metal for lowering into the water to keep a ship from moving.
Styrofoam is lightweight and contains a lot of air pockets, which provide buoyancy when placed under water. This buoyancy helps to keep the boat afloat even when it's carrying a heavy load.
