Is it possible to boil water in a paper cup?
The paper cup in which water is placed is having ignition temperature higher than the boiling point of water, and water have high latent heat of vaporization. This is also possible that temperature provided to water does not exceed its boiling point. Hence, water can boil in paper cup without burning the cup.
Can you boil water in a paper cup in the microwave?
Paper hot cups and soup cups are designed to hold hot drinks and food, but not to withstand the extreme heat of a microwave. At best, the glue at the seam can loosen and the cup will start to leak. … We recommend microwaving in glass or ceramic containers labeled as microwave safe.

Can you boil water in a paper cup over an open flame?
Boiling Water
This is nothing new, but you absolutely can boil water in a paper cup. Just make sure heat doesn’t come too close to the portion of the cup that does not have liquid, because if it’s dry, it will burn. Make sure you have a pair of tongs to remove the cup from the fire.
How can water boil in paper cup without burning it?
Water can be boiled in a paper cup because, the heat energy supplied to paper cup rapidly passes on to water. Thus, ignition temperature of paper is not achieved and, hence, it does not catch fire.
Is it safe to put boiling water in a Styrofoam cup?
Foam cups are made of styrene, a likely carcinogen. Putting hot liquids in them likely causes styrenes and any other trace chemicals to enter the liquid.
