Which cup keeps hot water the hottest polystyrene or metal?
Polystyrene (especially the expanded "Styrofoam (R)" type) is a good insulator. Metals are good conductors of heat.The insulating cup will maintain a greater heat differential than the conductor so if there is a liquid in the cup that is at a greater temperature than the surroundings, the metal cup will loose more heat than the polystyrene cup.
How do you keep a cup cold?
You can keep a cup cold by using a double-walled insulated cup, adding ice cubes, or placing the cup in the refrigerator or a cooler. Additionally, using a coaster or a sleeve can help insulate the cup and keep it cold longer.
Is a polystyrene cup a insulator or a conductor?
A polystyrene cup is an insulator. It is made of a non-conductive material that does not easily transfer heat or electricity.
Why would a polystyrene cup be a good insulator of heat?
Polystyrene is a substance that when in a solid state has a lot of holes. These holes trap air inside them and since air is a good insulator, the polystyrene cup is a good insulator. *Air is only a good insulator when not moving, hence why a breeze feels cold.
Why do people place coolie cups foam cup holders around their canned drinks?
People use coolie cup foam holders to insulate their canned drinks, helping to keep them colder for longer periods of time. The foam material provides a layer of insulation that prevents heat transfer from the surrounding environment to the drink inside the can. Additionally, the foam can absorb condensation from the cold drink, keeping hands dry and preventing slips.
How does a polystyrene cup keep drinks warm?
because it does
Will a metal cup keep a drink cold?
yes
How can a polyfoam container keep food warm?
well a polystyrene cup conducts heat so that is how it keeps your drink warm
What cup would you use to keep a drink cold?
use a metal container to keep a drink very full
Does Styrofoam cups keep hot drinks hot or cold drinks cold?
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.
Which cup keeps hot water the hottest polystyrene or metal?

Metals are good conductors of heat.The insulating cup will maintain a greater heat differential than the conductor so if there is a liquid in the cup that is at a greater temperature than the surroundings, the metal cup will loose more heat than the polystyrene cup.
What is Raw material of a polystyrene cup?
The raw material of a polystyrene cup is polystyrene plastic, which is derived from styrene, a petroleum-based hydrocarbon. The polystyrene undergoes a process called extrusion or injection molding to form the shape of the cup.

What cup keep your drink warmer?
Styrofoam
Is a polystyrene cup a insulator or a conductor?
A polystyrene cup is an insulator. It is made of a non-conductive material that does not easily transfer heat or electricity.
Why can you hold a hot drink in a polystrene cup without burning yourself?
The polystyrene is a foam consisting of a lot of air pockets that do not transfer heat quickly. It does depend upon the thickness of the polystyrene. Thinner ones will transfer heat quicker.
Will a tin cup keep a drink warm?
Of Course
