Question

what is the difference between Bar and atmosphes​

Answer 1

Answer:

Atmosphere originally was a unit related to the air pressure at sea level. It was later defined as 1.01325 x 105 pascals.

A bar is a pressure unit defined as 100 kilopascals. This makes one atmosphere nearly equal to one bar, specifically: 1 atm = 1.01325 bar.
