Question

ventilation allow in our room​

Answer 1

Answer:

A proper ventillation is maintained in a room because of convection currents in air. The process by which impure, warm air inside a room is continuously replaced by fresh air from outside is called ventillation. Breathing by people in a room increases the CO2 and humidity in air. The moist warm air containing CO2 is light and hence rises up. It then escapes through the ventillator, decreasing the air pressure in the room. Thus, the fresh cold air from outside flows in. Hence a continuous circulation of air is maintained within the room by convection currents.
