Consider a mixture of air and gasoline vapor in a cylinder with a piston. The original volume is 0.09 L. If the combustion of this mixture releases 900. Jof energy, to what volume will the gases expand against a constant pressure of 670. torr if all the energy of combustion is converted into work to push back the piston? (1 atm = 760 torr, 1 L atm = 101.325 J) a. 10.00 L b. 10.17 L c. 1.47 L d. 1.34L

10.17 L volume is required for the gases to expand against a constant pressure of 670.

Explanation:

The given data is as follows.

          = 0.09 L,      P = 670 torr

As,  W = 900 J       (given)

so,       =

           = 8.882 atm L

Now, we will change pressure into atm as follows.

            P = 670 torr

               = atm

               = 0.8816 atm

Therefore, we will calculate the final volume as follows.

          W =

    8.882 =

        = 10.08

            = 10.17 L

Thus, we can conclude that 10.17 L volume is required for the gases to expand against a constant pressure of 670.

the major pests we deal with are insects, weeds and fungal diseases. a pesticide is a product, whether organic or chemical, used to kill the target pest. there are other techniques gardeners should use that can prevent the severe infestations that make the use of pesticides necessary
