Why do convection currents rise in air?

Answer 1

Due to Charles's Law.

According to Charles's Law, temperature and volume are directly correlated, so when an air parcel gets hotter, its volume will increase. However, since the air's mass remains constant, its density must also decrease (density is defined as mass over volume), and as a result, the air will rise.

Answer 2

Convection currents rise in air because when air is heated, it becomes less dense and therefore rises. As it rises, cooler air moves in to take its place, creating a continuous cycle of rising warm air and sinking cool air, known as convection.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
