Question

Experimental proof for water is a bad conductor of heat

Answer 1

Answer:

Take a hard glass test-tube and drop it in a tiny cube of ice, wrapped in a wire gauze. fill 3/4 of the tube with ice cold water and then set up the apparatus as shown in the diagram.

Heat the test tube near its mouth. It is observed that in a few moments water starts boiling near the top, but the ice at the bottom does not melt. This experiment shows that water is a poor conductor of heat.
