Why do styrofoam cups keep water hot for longer than and paper cups?
It's a better insulator
Is glass a better insulator than styrofoam?
no
Is styrofoam a better insulator than wood?
Yes
Is cardboard a better insulator than styrofoam?
No, it's not
Is Polystyrene a good thermal conductor?
No, it's not, though it's better than you might think if you equate polystyrene with Styrofoam. Styrofoam is made of polystyrene, but it's the trapped air that makes it such a good insulator.

It's a better insulator
Is glass a better insulator than styrofoam?
no
Is styrofoam a better insulator of heat than plastic?
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.
Is styrofoam a better insulator than wood?
Yes
Is cardboard a better insulator than styrofoam?
No, it's not
Is a metal cup a better insulator or a plastic cup a better insulator?
Putting the cup in the freezer keeps ice from melting. Those cups will slow down the melting rate, but if you've got ice at room temperature it's gonna melt eventually. Having said that, ice will melt slowest in a styrofoam cup.
How can you determine if foam is a better insulator than paper?
yes you can test it under a lamp and see the temp. for the foam and paper and if one has the lowest than that's the better insulator!good luck!
Is the density of styrofoam less than paper?
nobc the Styrofoam is heavyer than paper
Is cotton a better insulator than aluminium foil and tissue paper?
No, cotton is not a better insulator than aluminum foil and tissue paper. Aluminum foil is a good insulator as it reflects heat, while tissue paper acts as a thermal barrier. Cotton, on the other hand, is not as effective of an insulator because it does not have the same reflective or thermal barrier properties.
Is Polystyrene a good thermal conductor?
No, it's not, though it's better than you might think if you equate polystyrene with Styrofoam. Styrofoam is made of polystyrene, but it's the trapped air that makes it such a good insulator.
Is a plastic cup a better insulator than a paper cup?
Plastic is an insulator. but most of the paper is not insulated, because the paper in general contains water, although the content is very low, but enough to pass current, but there also is a special insulation paper, that is on the special purpose. so in dry conditions, and the cup has no water, a plastic cup is a better insulator than a paper cup.
How well does styrofoam conduct heat?
Yes, styrofoam is full of air cells and air is a good thermal insulator. Styrofoam has poor solvent resistance, and poor hot performance.
