Next two problems have to do with the following situation. A sample of monatomic ideal gas is changed from state A to PIsotherms state D. The gas first undergoes an isobaric process A - E and then an isothermal process E - D. Note that relevant parameters (pressures and volumes) are directly given on the graph. (Note that these problems are 2 atm -- -- directly taken from your HW assigned during a class. We have...
