Question

define pressure briefly (for 5-6 marks question)​

Answer 1

Answer:

Pressure (symbol: p or P) is the force applied perpendicular to 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 (atm) is equal to this pressure, and the torr is defined as 1⁄760 of this.

SI unit: Pascal please give me points

Answer 2

Hi,

Pressure is the force that acts perpendicularly on a unit surface area. To obtain the value of pressure, we should divide the force acting on an object by the area on which it acts. Thus, the value of pressure is: Pressure = Force / Area.

The unit of pressure is Newton per square meter (N/m2), which is also known as Pascal.

1 Pascal = 1 N / m 2
