Question

3. Describe an activity to show that convection takes place in liquids.​

Answer 1

Explanation:

Take a beaker and half fill it with water. Drop some crystals of pottassium permanganate in it. ... The heat is transferred from the hot water at the bottom of the beaker to the cooler water at the top by the actual movement of the water itself.

Answer 2

Answer:

Explanation:

Take a flask filled 3/4 with water, keep it on tripod stand and let the

water to be still. Now add the potassium permanganate crystal into the

flask with the help of a straw. Heat the flask exactly below the crystal.

You will see as the water temperature rises the water molecules near

to the crystal will move up and cooler molecules will move down. This

process continues till whole water gets heated. This mode of heat

transfer is known as convection.
