Is rubber a best insulator or polystyrene?
Polystyrene is a better insulator than rubber. This is because polystyrene has a lower thermal conductivity, meaning it is better at reducing heat transfer compared to rubber. Additionally, polystyrene is often used in applications where higher levels of insulation are required.
Which is a better conductor wood or polystyrene?
Wood is a better conductor of heat than polystyrene. Polystyrene is a poor conductor of heat, making it a good insulator. Wood, on the other hand, conducts heat more efficiently due to its molecular structure.
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.
Why is polystyrene a better insulator than wool?
Polystyrene has a lower thermal conductivity than wool, meaning it is a better insulator. Polystyrene is a synthetic material with a closed-cell structure, which reduces heat transfer through conduction. Wool, being a natural fiber, has a higher thermal conductivity and can absorb moisture, affecting its insulating properties.
Is water or polystyrene a better insulator?
Polystyrene is a better insulator than water because it traps air molecules within its structure, creating a barrier to prevent heat transfer. Water, on the other hand, is a good conductor of heat and can easily transfer heat energy.

Is Polystyrene a good thermal conductor?
No, polystyrene is a poor thermal conductor. Its structure with trapped air pockets makes it a good insulator, which means it does not conduct heat well. This makes polystyrene commonly used in thermal insulation applications.
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 plastic a better insulator than metal?
Plastic is generally a better insulator than metal because it has higher electrical resistance and lower thermal conductivity. This property makes plastic a good choice for applications where electrical insulation or heat retention is needed. Metal, on the other hand, is a better conductor of heat and electricity.
Is glass or metal a better conductor?
Glass has a higher conductivity than thin plastic but,it is still lower than metal so metal may be a better conductor
Is polypropylene better than polystyrene?
That depends on how you define "better" and what you're using it for.
Is a knights armor a better insulator than a winter coat?
Nope. It's metal. Metal isn't a good insulator. It gets cold or hot too easily. A winter coat easily maintains a warm state most often.
What Lightning is more likely to strike a metal tower than a rubber hose because?
metal is a conductor and rubber is an insulator
