Question

The difference of pressure between two places is known as pressure

Answer 1

Answer:

In Science pressure is equal to the net amount of force acting per unit area. Dimensional Formulae of force is M1L1T-2 and of area is L2. Therefore Pressure's dimension can be obtained by calculating Force by Area. Dimensional formula of pressure difference is M1L-1T-2

But the atmospheric pressure on the surface of the liquid remains the same. Thus, there is a difference between the pressure inside the straw and the pressure outside the straw (pressure difference). ... Fluids flow from areas of high pressure to areas of low pressure. Pressure is the force applied per unit area
