Question

example of effect of atmospheric pressure

Answer 1

Effects of atmospheric pressure:
1. Due to atmospheric pressure, the ink gets sucked up in the fountain pen
2. Nose bleeding is a common phenomenon. The atmospheric pressure is low at high altitudes. But the pressure inside the human body does not change. thus pressure inside the body is much higher than atmospheric pressure due to which the valves in the junction of nose and eyes burst.
3. Atmospheric pressure helps in drinking water with a straw.
4. Due to atmospheric pressure, the liquid rises in a syringe when the piston of the syringe is pulled up.

Answer 2

Answer_____♥️

Applications of pressure:-

1) A syringe consists of a tight-fitting piston which moves in a cylinder, with a nozzle at one end also works with the help pressure.

2)When air is sucked out of a drinking straw ,the air pressure inside it decreases and the atmospheric pressure outside forces the liquid to go inside the straw.

3)A vacuum cleaner has a fan inside that creates a low pressure inside the device . Consequently,air and dirt particles are sucked into the device.

4)Siphon is only a rubber cylinder utilised for exchange fluid with the help of pressure.
