One simple method is to place the paper cup inside a second paper cup. The air gap between the cups provides a fair amount of insulation and slows heat loss.

When you Place A Cup Of Sand And A Cup Of Water In The Sun Which One Will Heat Up Faster?
The sand is most likely to heat up faster, particularly if it is dark. The water will have some evaporation, which will keep it cooler. It can also vary by how it is subjected to the sun's heat, like a flat pan or a colored cup, or clear vessel.
What happens when you put a filled plastic water bottle in an open fire?
In the first place the water in the bottle would keep the temperature of the plastic down preventing it from burning and leaking, The same as you would do by boiling water over a flame in a paper cup, However the water in the bottle would heat up and eventually the pressure inside the bottle would burst it like a balloon.
Do non disposable cups keep water hotter than disposable?
The Paper Cup Manufactured using GANA JBZ A-12 Paper Cup Manufacturing Machine will not keep water as hot the water kept in a glass cup.This is because the paper with loycoated has less capacity to hold the water or the liquid hot.It may start leaking after a point once the water gets chilled
Which is the more flexible - paper cup or metal nail?
Of course a paper cup would be more flexible. Nails are hard to bend.
Which can transfer more heat a cup of boiling water or a cup of tap water?
A cup of boiling water since it has higher temperature. Note that heat transfer depends more on the temperature.
What can you add to a paper cup to keep hot drinks hot for longer?
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.
How do you keep hot water hot in a cup?
try covering the glass, so the heat particles stay inside the cup, and the hot water stays hot.
Does a paper cup keep water hotter than a plastic cup?
no
Can a paper cup keep drinks cold?
Not for long.
Will a metal cup or a styrofoam cup keep the hot water warm after a short time?
It is the Styrofoam cup as it is not a good conductor of heat but the metal cup is a good conductor of heat.
Why doesn't a paper cup keep coffee hot for very long?
Insulation depends on the amount of air trapped between two layers. Paper has almost no air inside, while styrofoam, which has a very good insulative property, has a lot of air trapped inside of it.
Does the color of a cup affect how fast ice melts?
if the cup is dark colored then it absorbs more heat and thus help in melting the ice more quickly.This is also the principle behind usage of dark colored sweaters. ANSWER The color of the cup does not matter. It is the material that the cup is made of that maters. If it is an insulator of heat or not. A white styrofoam cup will keep a liquid hotter longer than a black paper cup.
Can a paper cup keep a hot drink warm?
i don't nown
WHY styrofoam cups keep liquid hot and cold?
Heat cannot travel through the foam material so the drink stays well insulated inside the foam cup.
Why does a polastyreane cup feel warm?
A polystyrene cup feels warm because it is a poor conductor of heat. This means that heat is not transferred easily from the outside of the cup to the inside and the cup is unable to dissipate the heat quickly. Instead the heat generated by the liquid inside the cup is trapped making the cup feel warm to the touch.The material of a polystyrene cup is designed to insulate meaning it does not easily transfer heat. This means that heat generated by the liquid inside the cup is retained causing the cup to feel warm to the touch. Other materials such as metal or ceramic are much better conductors of heat and are better able to dissipate heat quickly.The following characteristics of polystyrene make it a poor conductor of heat:Low thermal conductivityHigh resistance to heat transferLow thermal diffusivityWhen a polystyrene cup is filled with a hot liquid the heat of the liquid is not easily transferred out of the cup making it feel warm to the touch. This is why polystyrene cups are often used for hot beverages.
What makes a paper cup a good insulator?
A paper cup is not the best insulator. A better insulated cup is the foam cup. However, it is better insulated than other materials such as a metal canteen, due the the heat capacities of the materials. Putting two paper cups to together acts as a decent insulator due to the air between the two cups. This is due the to air being a poor conductor of heat.
How do you know if air takes up space?
because it has volume plus try this expeiment bring a big bucket and fill it with 15 cm of water and bring a cup and put to crumbled peices of paper and put it straight through the water and keep your hand on the cup while its in the water then after a minute pull it out and youll find no paper or inside of the cup is wet k bye
