Question

How do you represent pressure numerically? What is the SI unit of pressure? Define it.​

Answer 1

Pressure is the amount of force applied perpendicular to the surface of an object per unit area and the for it is p (or P). The SI unit for pressure is the pascal (Pa), equal to one newton per square metre (N/m2, or kg·m−1·s−2).

Answer 2

$pressure \: is \: represented \\ \\ {10}^{5} pascals \: \: and \: 1 atm = 101325 Pa = 760 torr. \\ \\ \\ si \: unit = pascals$

hope this helps u ✌️
