Answer 1

Experiment to prove that water is a bad conductor of heat energy

1. Take a hard glass test tube and drop a piece of ice wrapped up in copper wire gauze.
2. Fill 3/4th of the test tube with ice-cold water and clamp it in an iron stand.
3. Heat the test tube near its mouth with the help of a burner.
4. After a few moments, we can observe that water near the top starts boiling and steam is given off freely.
5. The ice placed at the bottom does not melt because the heat supplied to the water is unable to melt the ice.
6. This shows that water is a bad conductor of heat.
