Q.4 You want to buy a house. Would you like to buy a house having windows but no ventilators? Explain your answer.

Heated air being light rises up towards the roof and takes route through ventilators towards outside.
Q.5 Explain why holes are made in hanging banners and hoardings.
Ans.5 Holes are made in hanging banners and hoardings in order to equalise the air pressure on both sides of them. Higher pressure on one side of the hanging banners and hoardings may blow or torn them away when wind blows from one side at a high speed. Presence of holes allows air to pass through and prevents building up high pressure on one side.
