Question

write an experiment to observe the expansion of water due to heat?​

Answer 1

Observe the level of coloured water in the capillary tube. On heating the test tube, the air in the test tube expands and pushes the coloured water up. Stop heating the test tube and cool it. If the test tube is cooled, the air contracts and the level of the coloured water comes down to its original level.
