Question

Which of the following is an example of heat convection?

Answer 1

I believe it’s a liquid inside a beaker on a hot Bunsen burner (c)

This is because : Everyday Examples of Convection
Boiling water - The heat passes from the burner into the pot, heating the water at the bottom. Then, this hot water rises and cooler water moves down to replace it, causing a circular motion. Radiator - Puts warm air out at the top and draws in cooler air at the bottom.

Not sure if it’s right tho!

Answer 2

Answer:

Liquid inside a beaker on a hot Bunsen burner circulates and heats through constant motion.

Explanation:

Transmission of heat by convection requires the movement of a liquid or gas. An example would be liquid in a beaker heating up as hot and cold parts of the liquid constantly circulate, which further heats the liquid. Heat from the sun is considered radiation, and the other two answers are examples of conduction.
