The temperatures of 2.0 mol of ideal gas is increased from 150°Cto 250°C by two different process paths. In one, 2500 J of heat isadded to the system in the other, 3000 J of heat is added. (a) Whatis the change in the internal energy of the gas in each case? (b)In which case is more work done, and how much more?

A system of gases begins at pointp1v1and is transformed to the end atp2v2 on a pVplane. Three different paths areused for the transformation of thegases (a, b, c). The diagram isshaped like an eye with a linethrough the middle. The line throughthe middle is labelled b andthe top rounded part is a and thebottom rounded part c.p1v1 is at the point ofthe eye near thebottom and p2v2 is at thepoint near thetop.)
Assume 25 J of work is done on the gas by an externalsourcealong path a and 45 J of heat is added to the system. 20 J ofworkis donw along path b.
***If these are possible***, (if not possible pleasestatewhy)
