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.
What else can I help you with?
what type of cup keeps hot water hottest Paper or metal?
A metal cup will generally keep hot water hotter for longer compared to a paper cup. Metal is a better insulator than paper, so it helps to retain heat more effectively.
Which type of cup keeps cold water hottest plastic paper metal or glass?
No, paper will not keep water cold for the longest time. A metal cup will keep water the same temperature for the longest time. I know this because I did a science experiment about this but instead of cold water I used hot, which won't really make a difference. The next would be glass then paper.
Can polystyrene sink in water?
No, polystyrene is less dense than water, so it will float on the water's surface rather than sink.
Is polystyrene a conductor?
polystyrene along with other porous (objects which have a lot of air in them) such as Styrofoam water, wood and other materials are insulators, not conductors.
Is water or polystyrene a better insulator?
Polystyrene is a better insulator than water because it traps air molecules within its structure, creating a barrier to prevent heat transfer. Water, on the other hand, is a good conductor of heat and can easily transfer heat energy.
Which type of cup keeps hot water hottest polystyrene plastic paper or metal?
paper
What material keeps hot water hottest?
polystyrene
Which type of cups keep hot water hottest polystyrene plastic glass?
Polystyrene is a plastic. I think you meant "polystyrene foam", which would be correct.
What colour cup keeps hot water the hottest?
white
what type of cup keeps hot water hottest Paper or metal?
A metal cup will generally keep hot water hotter for longer compared to a paper cup. Metal is a better insulator than paper, so it helps to retain heat more effectively.

Is polystyrene less dence than water?
yes polystyrene is ls less dence than water because it floats
Can polystyrene sink in water?
No, polystyrene is less dense than water, so it will float on the water's surface rather than sink.
How does oiling of metals prevent rusting?
The oily layer prevents water and air from reaching the metal's surface and causing the metal to rust.
Why are lifesaving rings made of Polystyrene?
Life rings are often made of polystyrene because it is lightweight, durable, and floats on water. This makes it easy to throw to someone in distress and provides buoyancy to keep them afloat until rescue. Additionally, polystyrene is resistant to water damage and can withstand exposure to the elements.
How does painting prevent rust?
Painting a material that rusts, usually an iron rich material like steel, keeps the metal from exposure to the environment such as air and humidity. Rust is actually the oxidation of metal, and protecting metal with paint does not allow this to happen.
Water keeps running after shutting faucet off?
Replace rubber washers and possibly metal seats in the faucet
