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.
Why is an experiment performed in a polystyrene cup and not in a glass beaker?
The polystyrene cup is a better insulator than metal, metal is a good conductor of heat and so would transfer the heat from the reaction to the air outside it, where polystyrene keeps the heat inside. This enables you to get a much more accurate reading, as less heat has escaped.
Is uranium a metal nonmetal metalled?
Uranium is a metal, rather than a nonmetal, or metalloid.
Are plastic cups better than polystyrene cups?
The majority of plastic cups can be reused or recycled. Polystyrene, or foam, cups are not widely recyclable. Cost wise, plastic cups tend to more inexpensive than polystyrene cups.
Charge carriers in a metal are electrons rather than protons because electrons are?
loosley bound.
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.

Is metal stronger than styrofoam?
Yes, metal is very much stronger than Styrofoam. Note, Styrofoam is a brand trade mark, forextruded polystyrene foam, much used as an insulator and packaging material.
Which has more crystalline atactic polystyrene or syndiotactic polystyre?
The atactic polystyrene is more crystalline than the syndiotactic polystyrene.
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.
Does a polystyrene cup hold more heat than a plastic cup?
Polystyrene

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.
What are the advantages of using a plastic food container instead of a metal one?
Plastic food containers are usually see-through and allow people to see what is in the container. Plastic containers have an advantage over metal in that they do not rust. Plastic is also lighter than metal.
Is rubber heavier than polystyrene?
Yes.
