Referring to Problem, suppose the gas is expanded along processes 3 and 4 in Figure 18–26. On process 3 the gas expands at constant pressure from an initial volume of 1.00 m3 to a final volume of 3.00 m3. On process 4 the gas is heated at constant volume from an initial pressure of 106 kPa to a final pressure of 212 kPa. (a) How much heat is added to the gas during these two processes? (b) How much work does the gas do during this expansion? (c) What is the change in the internal energy of the gas?

Problem

Consider the expansion of 60.0 moles of a monatomic ideal gas along processes 1 and 2 in Figure. On process 1 the gas is heated at constant volume from an initial pressure of 106 kPa to a final pressure of 212 kPa. On process 2 the gas expands at constant pressure from an initial volume of 1.00 m3 to a final volume of 3.00 m3. (a) How much heat is added to the gas during these two processes? (b) How much work does the gas do during this expansion? (c) What is the change in the internal energy of the gas?
