Question

what is pressure. on what factors does pressure depend upon

Answer 1

hi there!!


1.

continuous physical force exerted on or against an object by something in contact with it.

it depends upon force and area...!!

Answer 2

The force applied perpendicularly to an object's surface divided by the surface area over which it is applied, is called 'force'.

• Pressure is the ratio between the force being applied and the surface area being applied to.
• The pressure exerted on a surface "A", by a force of magnitude "F" Newton when applied perpendicularly to the surface area, is equal to the ratio of F to A.
• Pressure, P= F/A
• The unit of pressure is N/m², also known as Pascal.

Pressure depends on various factors-

1. Pressure depends on the force.
2. Pressure also depends on the area over which the force is acting.
3. In the case of a liquid, pressure is affected by the density of the liquid, depth of liquid, and acceleration due to gravity on the liquid.
4. The pressure of a gas depends on the temperature and volume of the gas.
