"when we blow air, air pressure is reduced deu to high wind speed but inside the bottle, pressure of air is higher that pushes paper ball out. "
explain this statement please
Answers
Answer:
Air
Explanation:
You already know that when air moves, it is called wind. Air moves from the region where the air pressure is high to the region where the pressure is low. The greater the difference in pressure, the faster the air moves. But how is the pressure differences created in nature? Is the difference in temperature involved? The following activities will help you to understand this.
The pressure exerted by air on all bodies at all times in all directions is called air pressure. When air moves at high speeds, it creates a low pressure area. The air inside a balloon exerts pressure in all directions, and makes it blow up. Air opposes the motion of a moving object. This is called air resistance. That is why you have to exert yourself and pedal hard when you ride a bicycle.
