Cheenu sets up an experiment as shown in the figure.

What do you think would Cheenu's observation and conclusion be?

A

Paper cup with water does not burn.

B

Temperature of water rises.

C

Paper cup loses the heat to the water by conduction.

D

All of these.

Text Solution

Verified by Experts

The correct Answer is:
D
If we heat the cup with water it does not burn but the water start boiling after some time because the heat supplied to the paper cup is transferred to water by conduction. So in the presence of water, the ignition temperature of paper is not reached. Hence, it does not burn.
