Styrofoam is an insulator, meaning it is hard for heat to travel through it. This means if you put cold water in it, it is harder fo heat from the outside to warm it up. Conversely, hot water will also stay hot.
I assume you mean polystyrene. At any rate, "foam" contains air bubbles within the solid plastic or medium. Air is an insulating material (bit of a generalisation, but don't know to what level you want to the information). This stops thermal convection occurring, and prevents heat entering the container, in much the same way as a vacuum flask or Thermos keeps a drink hot.
This should really be under physics or chemistry btw.
FYI I have an A level in Chemistry and Physics. Also studying Biology at degree level.
Idont know
Yes.
Styrofoam is used to keep drinks cold or warm.
Yes, because it does not conduct heat.
styrofoam, but warning fammable and unsafe for the environment!
yes and hot too. Insulation is a heat barrier -- it tries to prevent heat exchange between the two sides. Vacuum is the best. Then air. Metals are the worst. ====================
no it will just keep the drinks cold longer
styrofoam is an insulator. It only works if thematerial stored is already cold.
styrofoam cups keep you beverages hot or cold because they are awesome
Styrofoam is used to keep drinks cold or warm.
Usually food it packed in Styrofoam to keep it cold (or warm)
To keep cold food cold or hot food hot. Styrofoam is very good insulation.
To keep cold food cold or hot food hot. Styrofoam is very good insulation.
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 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.
If the Stainless Steel cup has no insulation the Styrofoam cup will keep it warm longer.
not sure but i think styrofoam or thermocol
Yes it would as insulators keep in the heat and keep it out depending on whether the item is hot or cold.
