styrofoam
because it does
Plastic is a poor conductor of heat, so a plastic cup can be considered a good insulator. It will help to keep hot drinks hot and cold drinks cold for longer periods of time compared to a material that is a good conductor like metal.
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.
No, a galss cup does not keep any drink warm long.
it can what is wired
A styrofoam cup can help to retain heat, but it is not as effective as materials like ceramic or insulated metal. Hot water in a styrofoam cup will cool down faster compared to using a better insulated material.
A flask. It also keeps drinks hot.
A double-walled insulated cup made of stainless steel or ceramic will keep hot water hot the longest due to its ability to retain heat and prevent heat loss. Vacuum-sealed tumblers are also effective in maintaining the temperature of hot drinks for an extended period of time.
A purpose of a cup dispenser is to dispense cups. A cup dispenser is typically used near a drinks vending machine, particularly those that serve hot drinks such as coffee.
No, It doesn't. If you want to keep hot water hot for a longer time use a polystirene cup.
The thermal conductivity decreases when a paper cup (or another paper cup) is added. Intuitively, the heat has to pass through more layers. This is Fourier's Law of Heat Conduction - lower thermal conductivity means less heat loss.
