# Can water be made to boil in a paper cup without the paper being burned?

Contents

(B) Ignition temperature of paper is higher than the boiling point of water. … Paper burns at a different temperature than boiling of water. Complete step by step solution: If a paper cup is held at a certain distance from the flame, then it can easily be used to heat some water in it.

## How can water boil in a paper cup without burning it?

It is observed that it is possible to boil water without burning the paper cup. This is due to the reason that the heat given by the flame is quickly transferred from the paper cup to the water. As a result, the temperature of the paper does not reach the ignition temperature and hence is not burned.

## Why does a paper cup filled with water not burn?

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.

## How does water in a paper cup becomes hot without the paper cup catching fire when heated?

Answer: This is because when we heat the paper cup containing water, then the heat supplied to the paper cup is transferred to water inside it by conduction. Due to continuous transfer of heat from Paper Cup to water , the paper cup does not get heated to its ignition temperature.

## Does wet paper catch fire?

Wet paper contains water which restricts it from reaching a sufficient temperature which provides enough energy to overcome the activation energy for the paper to react with oxygen. … It is only on reaction with oxygen that paper catches fire.

## What happens to the empty paper cup and paper cup with water in the below activity?

Paper cup which contains water do not burn till water is vapourised. This happens because heat introduced to paper cup containing water, goes to water. Additionally water keeps the ignition temperature of the paper cup below limit. This the cause that paper cup containing water does not burn.

## Can you boil water in a paper bag?

Boiling water in a paper bag sounds like an impossible task.
