Question

Explain pressure with an example? ​

Answer 1

Answer:

Hello " Dear friend "

here's your answer...

Pressure is defined as a measure of the force applied over a unit area. Pressure is often expressed in units of Pascals (Pa), newtons per square meter (N/m2 or kg/m·s2), or pounds per square inch. ... If a gas is enclosed in a balloon, pressure is detected as some of the molecules collide with the surface of the balloon

Answer 2

Answer:

pressure is the Force applied perpendicular do the surface of an object per unit area over which that force is distributed pressure may also be expressed in terms of standard atmospheric pressure the atmosphere is equal to this pressure and the torr is define as 1 / 760 of this.

there are four type of pressure.

1 absolute pressure

2 atmospheric pressure

3 differential pressure

4overpressure (gauge pressure)

explanation …EXAMPLE OF PRESSURE .a simple example of pressure may be seen by holding a knife to price of fruit if you hold a flat part of the knife against the fruit it won't cut the surface the force is a spread out of large area (low pressure)
