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.
Is polystyrene a better insulator than metal?
Yes, polystyrene is a better insulator than metal. Polystyrene has a lower thermal conductivity, which means it is more effective at preventing the transfer of heat compared to metal. Metal is a good conductor of heat, so it allows heat to pass through easily.
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.
What is a good conductor for keeping things cold paper or plastic?
paper is thicker thus is hold cold or heat.
What is a better heat conductor paper or plastic?
Paper is a better heat conductor than plastic because it allows heat to pass through it more easily due to its natural fibers. On the other hand, plastic is an insulator and does not conduct heat as effectively as paper.
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.

What is the function of a polystyrene cup in heat of neurtralization?
A polystyrene cup is used as a container to hold the reactants during the neutralization reaction. It helps to prevent heat loss to the surroundings, allowing the reaction to occur at a more controlled temperature. The cup also provides insulation to maintain the heat produced by the reaction within the system.
What composites are used in polystyrene?
In polystyrene, the composites commonly used are typically mineral fillers like talc and calcium carbonate. These composites help improve the mechanical properties and performance of the polystyrene, making it stronger and more heat-resistant.

Why does putting carrier bags filled with polystyrene in your fridge or freezer help the environment?
The polystyrene will insulate the area it fills making less room for heat transfer by convection, hence less energy will be used to maintain the temperature. However I would use plastic containers of drinking water, instead thus making it more economical! Padraic
What is the reaction of polystyrene and acetone?
The mixture of Polystyrene and Acetone results in the creation of a sticky residue as the Polystyrene beads dissolve into the Acetone. You can use Nail polish remover with Acetone. However, the chemical reaction occurs at a much more rapid pace with pure Acetone.
What is HIPS plastic?
HIPS High Impact Polystyrene is particularly suitable for thermoforming, it is a tough, rigid material and its high impact strength means it can be guillotined, punched, routered or sawn without difficulty.
What are the differences between expanded polystyrene and polystyrene, and how do these differences impact their respective uses and applications?
Expanded polystyrene (EPS) is a lightweight, rigid foam material made by expanding polystyrene beads. It is commonly used for insulation, packaging, and construction due to its excellent thermal insulation properties and shock-absorbing capabilities. Polystyrene, on the other hand, is a solid plastic material that is more rigid and dense than EPS. It is often used in food packaging, disposable cups, and other products requiring a solid plastic material. The differences in density and structure between EPS and polystyrene impact their uses and applications. EPS is preferred for applications requiring lightweight insulation and cushioning, while polystyrene is better suited for products that need a more solid and rigid material.
Does metal conduct more heat than plastic?
Yes, metals are better conductors of heat than plastic.
What is a good conductor for keeping things cold paper or plastic?
paper is thicker thus is hold cold or heat.
