For conversion of kPa and atm, the relationship is 1 atm = 101.325 kPa. So for 20000 kPa, the atm number is 20000/101.325=197.4 atm.

Answer : The correct option is, 197.4 atm

Solution :

We are given pressure of gas is \(2\times 10^4kPa\) and the conversion used for the calculation is,

1 atm = 101.325 kPa

or, \(1kPa=\frac{1}{101.325}atm\)

As, 101.325 kPa pressure of a gas = 1 atm

So, \(2\times 10^4kPa\) pressure of a gas = \(\frac{2\times 10^4}{101.325}\times 1atm=197.38atm\approx 197.4atm\)

Therefore, the pressure in atm is, 197.4 atm
