Depends on several things. First weather you mean which reaches its melting point fastest and melts first from a starting temp or somthing else. The type of metal and plastic.
Usually it's plastic.
Hope this helps!
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.
A plastic cup holds more heat because plastic can't take out heat. Glass conducts heat away.
Water freezes faster in metal compared to plastic due to the higher thermal conductivity of metal. This means that heat is transferred more efficiently from the water to the metal, allowing it to cool down more rapidly. In contrast, plastic has lower thermal conductivity, leading to slower heat transfer and a longer freezing time for the water.
Good question! YES indeed metal does corrode faster than plastic!
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
An iPod is made out of glass,plastic,metal,wires,and a sensor for tough screen.
plastic, paper, glass, and metal are all recyclable.
Glass, Metal and plastic.
The heat conductivity of a container will influence the rate at which its contents lose or retain heat. Aluminum being a metal is a good heat conductor (better than glass or plastic at least) and would allow ice cubes stored in it to absorb heat more readily than the other two.
Silicone, hard plastic, metal, glass
