A cylinder with a moveable piston inside it holds a volme of air (Vi=0.129 m) at an initial pressure, P = 25.5 kPa. The piston moves so
that the final volume, V;, is 0.904 m; the temperature of the gas does not change during this process. (Soo the diagram shown.)
Answer the three parts below, using three sig figs.

Part A - This gas process would be classified as what?
Part B - Consider any work or heat flow occuring with this process. (Pick all the statements that are correct.)
There mus bo heat entering the gas somehow.
There must be heat leaving the gas somehow.
There is no heat entering or leaving the gas.
The environment is performing work on the gas.
Gas is performing work on the environment.
There is no work involved in this process.
The internal energy of the gas has increased during this process.
