Question

Suggest two ways in which ventilation can be improve.

Answer 1

 Open the windows to let fresh air in.

 If possible, open windows that are in two different directions or two different sections of the house, so that there is a cross breeze. This will create a wind tunnel, so that the air can enter from one end and leave from the other. This is known as cross-ventilation.

• Turn on the fan. This will circulate the air, moving it around the room.

I hope this will help you.

Answer 2

Ventilation can be improved: 
1. By building more ventilators, especially in kitchens.
2. By keeping the doors and windows open.
3. By keeping the fan on which will help to circulate the air.
4. By not using air-conditioners at least in the day time.
5. By keeping at least one potted  plant in each room.
