Question

What is pressure? What is unit ? On what factor
dou not the pressure of gas depend? long answer​

Answer 1

Explanation:

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). Pascal is a so-called coherent derived unit in the SI with a special name and symbol.

Answer 2

Explanation:

Pressure is an important physical quantity—it plays an essential role in topics ranging from thermodynamics to solid and fluid mechanics. As a scalar physical quantity (having magnitude but no direction), pressure is defined as the force per unit area applied perpendicular to the surface to which it is applied. Pressure can be expressed in a number of units depending on the context of use.
