Boiling water in a pan is a good example of convection because the warm water rises and the cooler water sinks.

Answer : Option A

Explanation:

The process in which a liquid is heated to transfer thermal energy to the liquid in the form of heat is called as convection. For example, when water is boiled in a vessel at a certain temperature which is a good example of convection, the warm water rises and the cold water sinks because liquid above a hot surface expands and then the liquid rises.
