The boiling point of water is 100 degrees. However, the point at which paper burns is much higher than 100 degrees. When you boil water in a paper cup, all of the heat is transferred to the water, not the cup. When the water starts to boil, the paper stays unburnt. After the water has boiled through, there should be a small black mark on the base of the cup which can be easily removed.

How can a water be boiled in a paper cup?
A paper cup can be used to boil water by filling it with water and placing it directly over a heat source such as a stove or campfire. The water will boil due to the heat transfer from the flame to the paper cup, causing the water to reach its boiling point. The paper will char and may eventually catch fire, so this method should be done with caution.
How can I safely boil water in a cup?
To safely boil water in a cup, fill the cup with water and place it in the microwave or on a stovetop. Heat the water in short intervals, stirring in between, until it reaches a rolling boil. Use caution when handling the hot cup to avoid burns.
How can water be boiled in a paper cup without causing any damage to the cup?
This is according to the law,the exchange of heat energy always takes place from a body at higher temperature to a body at a lower temperature until a thermal equilibrium is established between the hot and cold body.so the water can boil in a paper cup before the temp of cup equal to the water.
You can boil water in a paper cup over a direct flame without burning it How can you explain that?
This is only how i explained it to myself after i did the experiment, so it might not be right. Burning is the result of a combustion reaction, and combustion reactions require a certain amount of activation energy to start. When the paper is in contact with water, the energy from the open flame that would usually start the combustion reaction is transferred to the water before the paper can ignite. This raises the temperature of the water and it will eventually reach boiling point. Now when all the water has evaporated, then the cup burns because there is nowhere left for the heat to be transferred to.
How long does it take for water to boil in a foam cup?
It typically takes about 5-10 minutes for water to boil in a foam cup. However, caution should be exercised when boiling water in a foam cup as it can potentially melt or catch fire due to the heat. It is not recommended to boil water in a foam cup for safety reasons.
Can you boil water in a Styrofoam cup over an open flame?
Oh, dude, can you boil water in a Styrofoam cup over an open flame? Technically, yes, you can, but I wouldn't recommend it unless you want a side of melted cup with your water. Styrofoam is not exactly known for its heat resistance, so maybe stick to a regular pot for your boiling adventures.
What are some catchy titles for science fair project about boiling water in paper cup?
While is SOUNDS impossible, yes. you can- under the right circumstances. It requiress an exact balance between an even source of heat, and the wetting of the bag. Heat keeps the paper from getting too mushy, water keeps the paper from catching fire. This has been used for years as a Boy Scout camping entertainment. Not suggested that you try it indoors- parts of the bag above the waterline catch fire, and sometimes the bag comes apart.
How can colourless the coloured water?
Boil it with a cup and a lid on. Boil it for 10 minutes and open the lid. The water droplets under the lid will be colourless
Does a paper cup keep water hotter than a plastic cup?
A paper cup typically does not keep water hotter than a plastic cup. Paper is a poor insulator compared to plastic, so heat is more likely to escape from a paper cup, leading to faster cooling of the water inside.
How Do you boil hermit crab toys?
