Problem 1: Thermodynamic cycle A sample of a monatomic ideal gas occupies 5.00L at atmospheric pressure and 300K (point A in the following figure). It is warmed at constant volume to 3.00atm (point B). Then it is allowed to expand isothermally to 1.00atm (point C ) and at last compressed isobarically to its original state. 1) Find the number of moles in the sample. 2) Find the temperature at point B. 3) Find the temperature at point C. 4) Find the volume at point C. 5) Now consider the processes AB,BC, and CA. Describe how to carry out each process experimentally. 6) Find Q,W, and U for each of the processes. 7) For the whole cycle ABCA, find Q,W, and U
