Radha demonstrated one fun activity to her cousins. She kept a paper box filled with water on the stove flame as shown. Her cousins were surprised to find that the paper box did NOT catch fire for sometime. How can this be explained?
The stove flame cannot provide enough heat to reach the ignition temperature of the paper.
The water transfers the heat away, thereby keeping the paper below its ignition temperature.
Paper which is a poor conductor, cannot burn in the presence of a good conductor of heat.
The water starts boiling at temperature lower than the ignition temperature of the paper.
