Question

Which best describes how air moves during convection?
O
A. Cool air warms as it mixes with denser air.
O
B. Warm air cools as it falls through cooler, denser air.
O
C. Warm air rises as cooler, denser air falls.

Answer 1

Answer:

cool,dense air falls through warmer ,less dense air.

Explanation:

Answer 2

Cool air falls down and warm air rises during the moves of air in convection process. Thus,option C is correct.

What is convection?

Convection is process if heat transfer from one system to another system without direct connection of one system to another system.

In real you all noticed that if you leave a  cup of hot tea on a table it's gets cooled after some time. This is because heat is lost to the surrounding.

So when there is temperature difference between two bodies, heat is transfer from the hot body to colder body.

So in above question as warm air rises and cooler air falls because hot air have low density so it's rises and cool air have high density so it's cool down to surface.

Therefor, cool air falls down and warm air rises during the moves of air in convection process. Thus, option C is correct.
