Question

iii) What is a pressure and its unit?​

Answer 1

$\huge{\mathcal\red{♡Answer:}}$

Pressure—the effect of a force applied to a surface—is a derived unit, obtained from combining base units. The unit of pressure in the SI system is the pascal (Pa), defined as a force of one Newton per square meter. The conversion between atm, Pa, and torr is as follows: 1 atm = 101325 Pa = 760 torr.

There are several other units of pressure such as pounds per square inch and bar, unit of atmospheric pressure is atm, centimetres of water, millimetres of mercury or inches of mercury (used as a unit of blood pressure), torr, MSW and FSW.
