Question

Describe an experiment to show convection currents in a liquid

Answer 1

Answer:

On heating the bottom of the flask with a very small gas flame an upward current of colored water will ascend from the place where heat is applied. This colored stream reaches the top and spreads out. After a short time it circulates down the sides of the flask, showing that a convection current has been set up.
