What else can I help you with?
Why does a plastic fizzy drink bottle usually feel warmer than a metal can of drink even if they are at the same tmeperature?
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.
Can plastic scratch metal surfaces?
Yes, plastic can scratch metal surfaces because plastic is typically softer than metal.

Good question! YES indeed metal does corrode faster than plastic!
Why is plastic frame better than metal for double glazing?

Why do handlebars feel colder than normal?
The solid metal handlebars are colder because metal is a better conductor of heat/cold than rubber. Its like putting your hand in a 400 degree oven. your hand can stand the air because it is a poor conductor of heat. but you are burned if you touch the metal.

Are cutlery that have handles made of plastic more likely to break than metal ones are to bend?
Plastic is far more likely to bend than metal cutlery.
Does metal conduct more heat than plastic?
Yes, metals are better conductors of heat than plastic.
Why metal faster heat transfer than plastic?
I understand that this is for the same reason that a metal transfers electricity better: this is a result of a large number of free electrons, that is, electrons that are relatively free to move around.
Why are pots made of metal and handles of pots made of plastic?
Metals are good conductors of heat, so the heat from the stove is easily transferred to the food in the pot. Handles are made of plastic because plastic is a poor conductor of heat, so that the heat from the stove is not transferred to your hand when you grab the handle.
What are the advantages of using a plastic food container instead of a metal one?
Plastic food containers are usually see-through and allow people to see what is in the container. Plastic containers have an advantage over metal in that they do not rust. Plastic is also lighter than metal.
