8. (a) What do you understand by the term
Ventilation? How do convection currents in
air help during ventilation?​

Answer 1

Answer:

heya friend here is your answer....

Natural ventilation depends on winds outside and convection currents inside a building. Winds raise air pressure slightly on the windward side of a building and lower it slightly on the lee side. ... Convection currents are caused by the sinking of colder and therefore heavier air, which displaces the warmer air.

hope it helps
