Answer 2

10⁵ Pascals make 1 bar.

Pascal and Bar both are the units of measurement of Pressure.

• Pascal is the S.I. unit of measurement of pressure. 1 Pascal means if 1 Newton force is applied perpendicularly to an area of 1 m² then the pressure exerted by that force on that surface area is 1 Pascal.

                       ∴ 1 Pascal = $\frac{1 Newton}{1 m^2}$

C.G.S unit of pressure is Barye represented as Ba. This should not be confused with Bar.

• Barye is the  C.G.S. unit of measurement of pressure. 1 Barye means if 1 Dyne force is applied perpendicularly to an area of 1 cm² then the pressure exerted by that force on that surface area is 1 Barye.

                       ∴ 1 Ba= $\frac{1 Dyne}{1 cm^2}$

Now, 1 Dyne = 10⁻⁵ Newton

         1 cm² = 0.0001 m²

∴ 1 Ba =  0.1 Pascal

But, 1 Bar = 10⁵ Pascal.
