use a metal container to keep a drink very full
yes
Experiments were actually recently conducted on this specific subject. The verdict was that the foam cup was the best, followed by plastic, then the mug and a glass cup.
Styrofoam
To keep it cold, as the body temperature of the hand can warm the drink.
styrafoam.
Of Course
A normal plastic cup.
Not for long.
a type of cup that will keep a drink warmer is a thermos, you can get them in many different sizes (cup sizes). they can be found in any household goods stores even woolworths.
Heat cannot travel through the foam material so the drink stays well insulated inside the foam cup.
No, a galss cup does not keep any drink warm long.
A Styrofoam cup will do both. The Styrofoam is an insulator, and, as such, it slows the transfer of heat between the system (the drink) and the surroundings (everything outside the cup) If it is a cold drink, heat moves very slowly through the cup toward the drink. If it is a hot drink, heat moves very slowly through the cup toward the surrounding air.
