Question

If the pressure of a gas is 2.42 atm, what is its pressure in kPa?

0.00318 kPa
0.0239 kPa
245 kPa
1,840 kPa

Answer 1

kPa = atm x 101.325
kPa = 2.42 x 101.325
kPa = 245

Answer 2

Answer is: 245 kPa.

1 atm = 101.325 kPa.

p = 2.42 atm; the pressure of the gas.

p = 2.42 atm · 101.325 kPa/atm.

p = 245.20 kPa.

Atmospheric pressure (atm) is the force per unit area by the weight of air above that point.

Kilopascal (kPa) is a metric system pressure unit and equals to 1000 force of newton per square meter.
