A Styrofoam cup will do both.
The Styrofoam is an insulator, and, as such, it slows the transfer of heat between the system (the drink) and the surroundings (everything outside the cup)
If it is a cold drink, heat moves very slowly through the cup toward the drink.
If it is a hot drink, heat moves very slowly through the cup toward the surrounding air.

∙ 14y agoA styrofoam cup will retain the heat of a liquid longer than a typical plastic cup. This is because styrofoam material is comprosed of "foamed" polystyrene with millions of small air pockets. These air pockets serve as small insulators to slow down the heat conduction through the cup. For further information, suggest searching methods of heat transfer and Fourier's Law.

Why does styrofoam cup keep drinks hot longer?
Styrofoam is an excellent insulator.
Is styrofoam a better insulator of heat than plastic?
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.
What type of cup keeps water warm the longest-plastic paper styrofoam or glass and why?
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.
Is a metal cup a better insulator or a plastic cup a better insulator?
Putting the cup in the freezer keeps ice from melting. Those cups will slow down the melting rate, but if you've got ice at room temperature it's gonna melt eventually. Having said that, ice will melt slowest in a styrofoam cup.
How do copper cups keep drinks cold?
They don't. It feels colder in your hand and on your tongue because it is the cold escaping the vessel at a faster rate than if it were a more insular vessel. The drink itself feels colder because the mixture is hydrophillic (wants to dissolve in water) and creates an endothermic reaction (absorbs the heat from around it).
How can styrofoam cups be used to keep coffee hot and cola cold?
styrofoam cups keep you beverages hot or cold because they are awesome
Does Styrofoam keep liquids warm?
Styrofoam is used to keep drinks cold or warm.
What is a catchy title for science fair project on type of cups that keep drinks the coldest?
Cold Cups or Keeping Your Cups Cold.
Which type of cup will keep a hot drink, warm longer paper, plastic, Styrofoam or glass?
Styrofoam cups are generally the best at keeping hot drinks warm for a longer period of time. This is because Styrofoam is an excellent insulator, meaning it does not conduct heat well and therefore helps to keep the temperature of the drink constant. Paper cups and plastic cups are also decent insulators, but they are not as effective as Styrofoam. Glass cups are poor insulators and are not recommended for keeping hot drinks warm.
What is the best cup to keep a drink hot?
Styrofoam cups will keep a hot drink warmer for a long time. Insulated cups will also keep your drink warmer longer.
How does styrofoam keep drinks hot?
it can what is wired
Why does styrofoam cup keep drinks hot longer?

What material of cup keep your drinks hot?
styrofoam
Which type of cup will keep a hot drink warm the longest?
Styrofoam cups because of what they are made up of
How does a styrofoam cooler keep cold?
styrofoam is an insulator. It only works if thematerial stored is already cold.
Why do you pack your food in Styrofoam?
Usually food it packed in Styrofoam to keep it cold (or warm)
Why is food packed in styrofoam?
To keep cold food cold or hot food hot. Styrofoam is very good insulation.
