Question

describe any five application of pressure​

Answer 1

syringes and needles have a fine pointed end so that the area of contact decreases and the pressure exerted increases

dams have a broad base because at a greater depth water exrets a great pressure on the walls of the dam . to withstand with pressure ,dams have abroad base it greater stability

the hulls of submarines are especiaslly strengthend to bear the huge pressure of the sea water

deep sea divers have to wear specially designed suits otherwise the huge pressure of the water will crush their bodies

during holi festival we use water pistons for throwing colours etc . these simple water pistons are based on air pressure

Answer 2

$\huge {\rm{\orange{Answer:-}}}$

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.
