styrofoam, but warning fammable and unsafe for the environment!
Examples are plastics, metal and glass. Dangerous chemicals and toxins are also non-biodegradable, as are plastic grocery bags, Styrofoam (polystyrene), and other similar materials.
A metal spoon - plastic does not conduct electricity
The plastic drink bottle feels warmer than a metal can because the metal can has a higher thermal conductivity compared to the plastic drink bottle. Thermal conductivity is the property of a substance to conduct heat, and the metal can, being made of metal, has a much higher ability to conduct heat compared with the plastic bottle. This means that when you touch the metal can, it draws out your own body heat faster than than when you touch the plastic bottle, so the can feels cooler.
Insulators wuch as wood, polystyrene and wool keep the heat in because the have trapped air inside them. I guess you would say that conductors (such as metal)keep the heat out because heat flows through them. Once they are warmed up and taken away from the heat, they start releasing the heat inside.
A transparent ruler may be a polycarbonate. An opaque-type ruler may be a polystyrene copolymer such as high-impact polystyrene (HIPS). Recycled polystyrene can be turned into rulers, among other things.
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.
No
Plastic pens are typically made of a combination of materials, including a plastic barrel, ink cartridge, and metal components such as the clip and tip. The plastic used in pens is often a type of polymer such as polyethylene or polystyrene, which provides durability and flexibility.
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.
it is used so it can help insulate the metal so it doesnt radiate to over 70degrees centigrade and keeps the inner core completely safe
No, paper will not keep water cold for the longest time. A metal cup will keep water the same temperature for the longest time. I know this because I did a science experiment about this but instead of cold water I used hot, which won't really make a difference. The next would be glass then paper.
metal cup because it has insulation
They are not made of just plastic, though. They also contain metal. The metal parts move towards or away from one another to make or break the circuit, while the plastic keeps them in place without itself conducting current.
No there metal not plastic the top has plastic
styrofoam, but warning fammable and unsafe for the environment!
The heat capacity of a plastic cup depends on the material it is made of. Generally, plastic cups have a low heat capacity compared to other materials like glass or metal, meaning they heat up and cool down quickly. This property makes plastic cups suitable for quick temperature changes, such as pouring hot or cold drinks.
