Answer
Pressure is simply the force exerted per unit area. In gases, the pressure is the force exerted per unit area on the walls of the container (due to the random motion of gaseous particles.)
It is a scalar quantity and hence has only magnitude.
It is represented by the Pa unit of pressure.
1 pascal = 1 $\frac{N}{m^{2}}$
Another unit of pressure is atm.
1atm = 101.325 Pa.
Another unit of pressure is the millimeter of mercury represented by mm Hg.
1 atm = 760 mm Hg.
