Answer 1

diffrence bw 1 atm and 1 bar presdure

1 atmosphe

1).One atmosphere is more or less arbitrarily defined as the amount of pressure
it takes to raise a column of mercury (Hg) to a height of 760 mm. It is

2).in some sense supposed to represent an "average" sea-level atmospheric
pressure.

bar pressure

1.) A bar is defined in terms of SI units, and is not directly related to any
physical phenomena. One bar is defined as 10^5 Pascals


2).(1 Pascal = 1 N/m^2). It's pretty much a coincidence that the two
units are equal to within just over a percent (1 atm = 1.01325 bar).
