Hint: The pressure is expressed in many units across the whole universe. Both \[bar\] and \[pascal\] are the units of pressure. Unit \[bar\] is defined as the atmospheric pressure acting on any body whereas S.I unit \[pascal\] is defined as the force per unit area on any body.
Complete step by step answer: Both are the units of pressure. As we know, the S.I unit of pressure is \[pascal\] which is defined as the one \[newton\] of force acting on the \[1{m^2}\] area. If we want to define the unit \[bar\] then it will be the atmospheric pressure that is acting on anybody.
Both are related as-
\[1bar = {10^5}pascals\]
\[1pascal = {10^{ - 5}}bar\]
So, 1 \[bar\] will be \[{10^5}\] times of 1 \[pascal\].
Note: Pressure is defined as the force exerted on an object. There are many types of pressure like- absolute, atmospheric, gauge pressure, vacuum pressure.
As we know earth’s atmospheric air is surrounded by many layers of gases and this air will exert some pressure that is known as atmospheric pressure. We can measure this pressure by using a mercury barometer. If we define absolute pressure, it exists in the air free space of the universe. It is the sum of gauge pressure and the atmospheric pressure.
Gauge pressure is positive for the pressures above the atmosphere and negative for pressures below it and vacuum pressure indicates the differences between atmospheric pressure and absolute pressure.
