Question

what are the two parameters used to define pressure?

Answer 1

The force applied perpendicular to the surface of an item per unit area across which that force is spread is known as pressure (symbol: p or P). The gauge pressure is the pressure in relation to the surrounding air pressure. Pressure is measured in a variety of ways. Some of them are derived from a force unit divided by an area unit; for example, the SI unit of pressure, the pascal (Pa), is one newton per square metre.

Complete step by step answer:
The force exerted and the area on which it is applied are the two factors that determine pressure. The force applied per unit area is referred to as pressure.
${\text{P = }}\dfrac{{\text{F}}}{{\text{A}}}$
Where P stands for pressure.
F stands for applied force.
A is the region where the force is delivered.
As a result, the applied force and the area on which the pressure is exerted are the parameters that characterise pressure.
Pressure is a scalar number that is defined as force per unit area acting in a perpendicular direction to the surface. Pressure is an important physical quantity that is used in a variety of fields, including thermodynamics, solid mechanics, and fluid mechanics.
Pressure is defined as the force per unit area applied perpendicular to the surface on which it is applied as a scalar physical quantity (having magnitude but no direction). Depending on the context, pressure can be represented in a variety of units. Because pressure is only determined by the force operating perpendicular to the surface, only the force component acting perpendicular to the surface contributes to the pressure imposed by that force on that surface. Pressure may be raised by increasing the force or lowering the area, or lowered by decreasing the force or increasing the area on the other hand.

Note:
In its most basic form, pressure is defined as force per unit area. When dealing with pressures exerted by gases and liquids, however, the definition of work ($W = Fd$) is the most practical way to approach pressure as a measure of energy per unit volume. Pressure is defined as force per unit area, and its definition as a measure of energy per unit volume is given in. Because the force operating on a system contributing to pressure does not operate on a single point or surface, but rather as a distribution of force, it is more suitable to analyse pressure as a measure of energy per unit volume for gases and liquids.
