Question

atmospheric pressure at a place is 720 mm of HG calculate its value in Pascal​

Answer 1

Answer:

Information needed for this:-

760 mm of Hg =1 atm.

1 atm=1.013×10^5 Pascal.

This implies that

760 mm of Hg = 1.013×10^5 Pascal.

Additional information:-

1 bar=10^5 pascal.

=0.98atm

1 atm =760 Torr =760 mm of Hg.

1 Pascal =1Nm^-2.
