Awell-insulated, closed device claims to be able to compress 100 mol of propylene, acting as a soave- redlich-kwong gas and with cp* = 100 j/(mol·k), from 300 k and 2 m^3 to 800 k and 0.02 m^3 by using less than 5 mj of work. is this possible?

Explanation:

The given data is as follows.

          Moles of propylene = 100 moles,     = 100 J/mol K

          = 300 K,           = 800 K

          = 2 ,   = 0.02

Therefore, the assumptions will be as follows.

                    = W

Putting the given values into the above formula as follows.

                  = W

         W =

              = J

              = 5 MJ

Hence, this shows that a minimum of 5 MJ work needs to be done.

Since, work is very less. Hence, it will not compress the given system to 800 K and 0.02 .      

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
