Question

Define 1 Pascal of pressure by giving the expression of pressure .

Answer 1

One Pascal is the pressure exerted by a force of 1 N on a body or object of area 1 m^2

Pressure = Force/Area

Answer 2

hi buddy
here's your answer looking for

we know that , pressure is nothing but the force exerted on per unit area.

so, mathematical equation can easily be given by

P=F/A

and we also know that the SI unit of pressure is Pascal.

so,

$1pascal = \frac{1newon}{1 {meter}^{2} }$
or,

the pressure is said to be one Pascal give you one newton of the force is applied on the area of 1 m square.

hope you are satisfied with my answer
