No.
You can boil water in a paper cup over a flame although you'll have more success if you have a steel grid in between so that the paper is heated evenly. The temperature at which paper burns is lower than that at which water boils so that the water keeps the paper too cool to catch light.
If you try the same with a styrofoam cup, it will melt. Because styrofoam is a good insulator, the water can't keep it cool enough to prevent it melting.

The water cools the cup.

What happens when you heat liquids?
It depends on what liquid you heat, and if is an open flame or just an element, like gas+open flame is very dangerous while water+open flame causes a reaction of steam to rise. im not the greatest at science but i know somethings, but somethings boil, some just evaporate and some do even more things but im not a science person siz
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.
When the air hole is half open what is the flame called?
Green flame cuz when the air hole is closed it is yellow and when it is open it is blue so when the colors are combined they make the green flame
Is a Bunsen flame hottest when the hole is open or close?
A Bunsen burner flame is hottest when the air valve hole is open.
What is the name of the flame when the air hole of a Bunsen burner is open?
Air hole fully open gives a 'roaring blue flame'

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
Do you open pouch of spices of a Crab boil?
DO NOT OPEN CRAB BOIL BAG. AFTER BOILING CRAB IN 212 degree WATER FOR 7 MINUTES, DISCARD BAG, DO NOT REUSE!
The process of combustion occurring without an open flame is called?
Non-open flame combustion
How do you boil water on an open fire?
By putting the water in a pan/pot and then hold the pan/pot over the fire until hot :)
Can you boil rubbing alcohol?
I am not sure about using alcohol; however, I can share with you depending on where the boil is located, soaking the area in warm water with Epsom salts, or a warm sitz bath is very effective in bringing the boil to a head. Hydrogen Peroxide is helpful if the boil is open. Many boils have to be lanced to allow the puss and infection to be released, whereby, the warm water/Epsom salt soaks/baths are more effective. The Epsom salt and warm water help to draw out the puss and encourage healing.
Can you pop a boil?
You can pop a boil but it is not recommended due the risk of further infection. You can make the boil come to a head by laying a washcloth rinsed in hot water over it. The will help the infection rise to the surface. As this happens the boil will open up and begin to drain.

What electric appliance do you use to boil water?
have you tried an electric kettle?Use an electric boiler 220 - 440 VWhen oil delivery or natural gas is not available or an open flame is impracticable such as ship board or medical facilities where oxygen or other combustible fuels are present or when one needs to "boost" the water temperature to kill bacteria or other water borne diseases
How do you change from a safety flame to a roaring flame?
to change from a safety flame to a roaring flame you would fully open the air hole.
Is a Bunsen flame hottest when the hole is open or close?
A Bunsen burner flame is hottest when the air valve hole is open.
