Why we can easily boil water in a paper cup?

Why we can boil water in a paper cup?

we can boil water in a paper while empty paper catches fire easily because the heat is continuously absorbed by the water which prevents the paper cup from burning…

Can we boil water in a paper cup If yes explain?

Water draws heat away from a heat source through convection until it reaches its boiling point of 100 degrees Celsius. … As the water heats up, it conducts heat away from the paper, preventing the paper from reaching that crucial temperature. Heat also continues escaping via the steam that’s created when water boils.

Why we can boil water in a paper cup on a spirit lamp?

Because heat passing to paper cup is absorbed by water and we can easily boil water in a paper cup.

Can you boil water in a paper cup in the microwave?

THIS IS MAGIC:  Can boiled eggs help with belly fat?

Why paper cup containing water does not burn which condition is not satisfied here?

If the paper cup is heated carrying water, the water will be absorbing the heat coming from the burning source and thus stops the paper from reaching its ignition point. Therefore it will not burn. … This is because of the absorption of heat by water in it.

Can you pour hot water in plastic cup?
