Question

True or False (3)
1. Ventilators are always at lower part of the room

Answer 1

Answer:

false

Explanation:

Ventilators are provided in the rooms at the top of the roofs because if the air inside the room gets hot, the hot air rises up and flows through these ventilators and thus cool air remains at bottom. It brings cool and fresh air in the room. Thus ventilators maintain conventional currents to keep the air fresh in the room.

It’s absolutely false
Because just think how could it can be at lower part of the room
