उत्तर
Water is a bad conductor of heat
An ice cube is wrapped into a wire mesh and is put at the bottom of the glass test tube. The test tube is then heated near the top of the water. It will be noticed that though the water at the top starts boiling, the ice at the bottom does not melt. This clearly shows that water is a poor conductor of heat.
