In the electrical trade it makes no difference which type of box you use. Both types are approved to be used as an electrical junction box. If the object is to keep costs down go with the plastic box. In harsher environments plastic boxes are used along with PVC plastic conduit.
We find that metal is a better conductor of heat than plastic or wood.
because the plastic is liter than the metal
For a lightning conductor, we need an electrical conductor, so the iron would be superior.
No. Plastic is a bad conductor of heat as it does not have free electrons and metal are good conductor of heat as they have one or two free electrons in outer orbit.
It is better to use a plastic baby spoon instead of a metal one. Metal spoons make it easier for babies to hurt themselves when they are first learning to use eating utensils.
Cookers are made of metal because it withstands heat a lot better and does not melt like plastic would.
i think the metal one would work better because it has better quality
No, it is not. Metals conduct heat much better than most plastics. However, if the metal is used as a reflector of radiated heat, it will insulate better than plastic would.
I would say that plastic cups are better for string telephones because you cant get string through a metal cup.
most likely metal
A plastic cup holds more heat because plastic can't take out heat. Glass conducts heat away.
it clings better to plastic
A metal spoon - plastic does not conduct electricity
We find that metal is a better conductor of heat than plastic or wood.
Between metal and plastic for collecting rainwater, plastic is better. The plastic is less harsh for the soil as well as the plants compared to the plastic barrels.
Metal is a better conductor
It is typically better to use plastic knobs over metal knobs on kitchen furniture. The plastic knobs tend to not scratch the floor as much as metal knobs.
