Describe an experiment about convection?​

Explanation:

Convection is the movement within a liquid (or air) when the hotter and less dense liquid rises, and the colder, denser liquid sinks due to gravity. These movements create the circulation patterns in our atmosphere through air and water. The warm water or air rises and allows cooler air (or water) to go underneath.

I hope it's helpful!!
