NCERT Solutions for Class 7 Science Chapter 8 Winds, storms and cyclones In Hindi PDF Download
FAQs on NCERT Solutions for Class 7 Science Chapter 8 - In Hindi
1. State two experiences that made you think that air exerts pressure.
We know that air exerts pressure and many examples justify this fact. Two such experiences which show that air exerts pressure are listed below:
Blowing a balloon: When air is blown into a balloon, it expands and the balloon becomes tight. The balloon bursts if this is continued.
Wind blowing at high speed: This causes windows and doors of houses to sway.
Both these instances occur because air exerts pressure.
2. Explain why holes are made in hanging banners and hoardings.
Air makes objects move, burst, sway, etc. This is because air exerts pressure that forces these objects in motion. Hanging banners become rigid surfaces for the air pressure to act. If holes are not made on their surfaces, there would be no other passageway for air to blow through. When there are holes on its surfaces, air pressure on the hoardings is less and they are not distorted.
