Detailed Solution

The above statement is true.
Pressure is the force acting on any object per unit area.
Explanation:
Let

1 N

of force act on

1 m^{2}

of area so the pressure exerted by that force will be
⇨

P = \frac{F}{A}

Here,

P

is pressure,

F

is force, and

A

its area.
And given that

A =

1 m^{2}

F = 1 N

⇨

P = \frac{1}{1}

⇨

P = 1 Pa

So we can say that pressure is a force acting per unit area acting on the surface.
According to Pascal's law, the pressure "External static pressure applied to a confined liquid is evenly distributed or transferred throughout the liquid in all directions."
