Styrofoam cup is a good insulator because it is coated with foam
Styrofoam is an insulator. It has low thermal conductivity, meaning it helps to reduce the transfer of heat and cold.
No, Styrofoam is a good thermal insulator but not the best. Materials like vacuum insulated glass or foam materials with higher R-values are more effective for insulation. Styrofoam still offers decent insulation properties due to its low thermal conductivity.
No, Styrofoam is not a good electrical conductor because it is an insulator. This means it does not allow electric current to flow easily through it.
Styrofoam is a good insulator because it has a low thermal conductivity, meaning it doesn't easily transfer heat. This property makes it useful in applications where thermal insulation is needed, like in packaging or construction.
Sawdust can serve as a good insulator, providing some thermal resistance, but it generally has a lower insulating capacity compared to materials like styrofoam. Styrofoam is specifically designed for insulation and typically offers better thermal resistance properties.
Styrofoam, along with most other expanded plastics, is a very poor insulator of heat and electricity, thereby making a foam coffee cup a very good insulator.

Styrofoam is excellent
Styrofoam is an insulator.
A metal cup would likely keep the hot water warmer for a longer period than a styrofoam cup due to its superior insulating properties. Metal is generally a better conductor of heat, so it is able to retain heat better than styrofoam, which is a poor insulator.
No, Styrofoam is a good thermal insulator but not the best. Materials like vacuum insulated glass or foam materials with higher R-values are more effective for insulation. Styrofoam still offers decent insulation properties due to its low thermal conductivity.
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.
Yes, styrofoam is full of air cells and air is a good thermal insulator. Styrofoam has poor solvent resistance, and poor hot performance.
A styrofoam cup is a better insulator than glass because it has a lower thermal conductivity. This means that it is less effective at transferring heat energy from the hot chocolate to the surrounding environment. Glass, on the other hand, has a higher thermal conductivity and allows heat to escape more easily. Therefore, the hot chocolate will stay warmer for longer in a styrofoam cup compared to a glass.
Styrofoam is a very porous material; air from the closed pores has a bad thermal conductivity.
