Question

State the SI unit of pressure.

Answer 1

Answer:

The S.I. unit of pressure is Pascal (Pa)

Answer 2

Answer:

Pascal (Pa)

Explanation:

As per the question,

The pressure is an expression of force applied on a surface per unit area.

                         $Pressure=\frac{Force}{Area}$

The standard unit used for the measurement of pressure is Pascal (Pa) which is equivalent to one newton per meter square written as $\frac{N}{m^{2} }$ . sometimes pressure is also measured in cgs  (centi gram system) unit that is dynes per centimeter square written as $\frac{dyn}{cm^{2} }$.The  Earth's atmosphere pressure at sea level is $10^{5} Pa$.It is also defined as the energy per unit volume.
