Answer and Explanation:
To convert 120 kPa to atmospheres, we can use the following conversion factor:
1 atmosphere = 101.325 kPa
We can use this conversion factor to set up a proportion and solve for the number of atmospheres.
120 kPa * (1 atm / 101.325 kPa) = 1.184 atm
Therefore, 120 kPa is equivalent to approximately 1.184 atmospheres (rounded to three decimal places).
