Yes cause plastic is a fossil fuel and donsaurs are dead therfore cold.
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.
Customized plastic cups are created mainly from recycled materials and Polyethylene terephthalate (aka, PET), a form of plastic widely used in the food and beverage industry to manufacture cups. They are heat and cold resistant, and are tough to break. Unlike other plastic cups such as PP and PS, PET cups are recyclable and its polymer chain can be reused. They are perfect options for juice, water, cold beer, and much, much more.
Metalic cups keeps the water cold and it can be also used to keep the water hot .
No.
Styrofoam because it has a thick layer and is a good insulator.Paper and plastic are could alternatives but Styrofoam would work better, therefore glass would be the worst one to use because it would only keep it warm for a couple of minutes.
Get 2 cups one plastic and 1 polystyrene and test which one will maintain the temperature of hot water for the longest. Record temp. every minute. I got an A when i did it
metal
Most supermarkets sell plastic cups.
It depends on the type of plastic being used. Hopefully the packaging label will let you know if it is intended for liquids, solids, hot, or cold. If you don't have that information, you should test it first. The same considerations apply to plastic spoons. Some spoons turn soft and collapse when in boiling water.
One can get plastic drinking cups from most supermarkets, party supply stores and even from home and office supply stores. Walmart has clear plastic cups. The Party People has clear, yellow, red and silver plastic cups. Redds Cups has red plastic drinking cups.
You can separate two plastic cups by pulling them apart in opposite directions or twisting them away from each other. Another method is to run hot water over the cups, which can help soften the plastic and make them easier to pull apart.
The majority of plastic cups can be reused or recycled. Polystyrene, or foam, cups are not widely recyclable. Cost wise, plastic cups tend to more inexpensive than polystyrene cups.
