Text Solution

Verified by Experts

The correct Answer is:
b
Take an empty test tube fit fits mouth with one holed cork stopper .Take a drop of coloured liquied into a narrow galss tube fit the narrow galss tube through the cork so that the level of the colured drop is just above the cork heat the tst tube and obser the positon of coloured drop in the narrow glass tube The trapped air in the test tube expands and it pulses the coloured drop upwards
