A mixture of nitrogen and argon gas is expanded from a volume of to a volume of 62 L to 84 L, while the pressure is held constant at 96 atm . Calculate the work done on the gas mixture. Round your answer to significant digits, and be sure it has the correct sign (positive or negative).

Explanation:

The given data is as follows.

        P = 96 atm,         = 62 L

      = 84 L

Now, we know that the relation between work and pressure is as follows.

          W =

Putting the given values into the above formula we will calculate the work done as follows.

            W =

                =

                = -2112 J

or,            = -211.2 kJ     (as 1 kJ = 1000 J)

Thus, we can conclude that the work done on the gas mixture is 211.2 kJ.

what is the question because that is not a question.

your answer is, orbit around the nucleus
