Question

The atmospheric pressure at a place is 75 cm of Hg. What will be

corresponding pressure in Pa. Show working
​

Answer 1

Explanation:

h=76cm

Pressure=?

Formula to be used : P=hgd

Where h = height of mercury column and

d= density of mercury=13.6gm/cc

acceleration due to gravity=980cm/s²

P=hgd=13.6×980×76=1012928dyne.cm²
