Polystyrene cups are lightweight, inexpensive, and provide good insulation for hot or cold beverages. They are also disposable, making them convenient for single-use purposes. In contrast, metal containers are durable and reusable but may not offer the same level of insulation and can be more expensive.

Is polystyrene a better insulator than metal?

Yes, polystyrene is a better insulator than metal. Polystyrene has a lower thermal conductivity, which means it is more effective at preventing the transfer of heat compared to metal. Metal is a good conductor of heat, so it allows heat to pass through easily.


Can polystyrene sink in water?

No, polystyrene is less dense than water, so it will float on the water's surface rather than sink.


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.


Can polystyrene pass UV light?

Polystyrene does not transmit UV light very well as it is a type of plastic that is typically opaque to UV radiation. UV light tends to be absorbed or reflected by the polystyrene material rather than passing through it.


Why is polystyrene useful as a clothing material?

Polystyrene is not typically used as a clothing material due to its characteristics. Polystyrene is more commonly known for its use in packaging and insulation due to its lightweight and insulating properties, rather than in the clothing industry.


Is polystyrene ball heavier than iron ball?

No, iron is denser and heavier than polystyrene. An iron ball would weigh more than a polystyrene ball of the same size.


How efficient is a kettle?

Very - probably well over 90%. An electric kettle is very efficient, especially if the body is made from plastic rather than metal; almost all of the electrical energy used goes into heating the contents rather than the container. A metal bodied kettle used on a gas stove would be significantly less efficient.


Is polystyrene less dence than water?

yes polystyrene is ls less dence than water because it floats


Is uranium metal a nonmetal or a metalloid?

Uranium is a metal, rather than a nonmetal, or metalloid.


Is uranium a metal nonmetal metalled?

Uranium is a metal, rather than a nonmetal, or metalloid.


Is styrofoam the same as polystyrene?

They are made from the same polymer, polystyrene. Usually polystyrene is clear, hard and rigid, for example in CD cases. However, styrofoam is created by blowing air through liquid polystyrene. The bubbles are locked in the polystyrene as it solidifies, giving the syrofoam used in packaging and cups. The reason it is compressible is because the air is compressed, rather than the hard, rigid polystyrene itself.


Is rubber heavier than polystyrene?
