Let us take some pure water in a test tube and dip a piece of wax in it after wrapping it in wire Then we hold the test tube in an inclined position and start heating water in the upper part of the tube we will observe that wax does not melt even when the upper part of water starts boiling Thus we can conclude that!!

Answer 2

Water is poor conductor of heat

AIM

• To show that water is a bad conductor of heat.

Materials Needed

• Test tube
• Water
• Ice
• Bunsen Burner
• Thin Wire

PROCEDURE

• Fill the test tube with water and put a small ice cube wrapped in wire gauze, in it
• Make sure that the ice cube is at the bottom of the test tube
• Heat the test tube from the top using a Bunsen Burner.

OBSERVATION

• The water will boil at the top of test-tube while the water at the bottom will be cold indicating that heat has not reached the bottom where the ice cube is present. This proves that water is a bad conductor of heat.
