Question

To show that a liquid expands on heating and contracts on cooling
• Take a beaker and fill it with coloured water.
• Close the mouth of the beaker using a lid.
• Fix a capillary steel tube through a hole in the lid. The tube should be dipped in water
• Check and note the water level in the capillary tube.
• Now heat the beaker by placing it in a water bath.
You will observe that the level of the coloured water drops down in the capillary tube.
This shows that liquid does not expand on heating.
