Pressure:-
Pressure is force per unit area.
To calculate pressure, we can use parameters as well as a manometer. We should use Mercury to calculate pressure by these Apparatus due to:-
The density of mercury is very high and we know that density is inversely proportional to the space of a moment. Mercury is non-volatile and does not react with the glass.
SI unit of pressure.
The SI unit for pressure is the pascal (Pa), equal to one newton per square metre (N/m2, or kg·m−1·s−2).
