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
Why do styrofoam cups keep water hot for longer than and paper cups?
It's a better insulator
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 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
Why do styrofoam cups keep water hot for longer than and paper cups?
It's a better insulator
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.
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.
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.
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.
Is fibreglass a better insulator than vacuum?
No. If you can get it, vacuum is the best insulator.
Which is the best insulator thermocol or air or cotton or aluminium?
Air is better than thermocol as insulator. .....
Is a material with a lower R-value a better insulator than a material with a high R-value?
No. A higher R-value is a better insulator.
