A plastic cup holds more heat because plastic can't take out heat. Glass conducts heat away.
NO! Metal is a better conductor than plastic. The metal would stay warmer for a longer amount of time. The plastic would cool off faster
cars don't have plastic radiators, if they do the plastic would probably melt, and the compound of metal cools and heats quickly which is useful in cooling water.
Water in a metal cup will freeze faster because metal conducts coldness and energy the most. trust me, I did a project with a metal, plastic, glass, and paper to see which cup would freeze the quickest. Hopefully this answer helped.
In general, foam is a better insulator than metal, and so foam would be expected to keep water hotter longer under most normal circumstances.
I think its a plastic.
a styrofoam cup. i tried it on my science project
Metal shower heads look nicer but show hard water, plastic will not show hard water, if you have a water softener a metal shower head is the way to go.
probably metal
When you put metal in water it cools down quick. When you put plastic in the microwave, you're in for a big problem....Plastic is the answer.
metal cup because it has insulation
It depends on how good a conductor the material is. Metal is a better warmth conductor then some plastics.
No, Plastic is not conductive! I other words plastic can not conduct electricity therefore it can not produce resistance, and resistance is what you need to produce heat. and that heat would melt the plastic. Now if you touch a "live" wire to metal and that metal was grounded ( for example to a cold water pipe) then you would be completing the circuit, then that piece of metal would heat up very rapidly and eventually melt! of-course the smart person would not do this but if you where not so smart be prepared to get burned!!!! BE SMART!!
it would melt faster in a glass container faster.
