- 50 GOA lab sample of gas is taken p through cycle abca shown in the p-V diagram of Fig. 18-43. The net work done is +1.2 J. Along path ab, the change in the internal energy is +3.0 J and the magnitude of the work done is 5.0 J. Along path ca, the energy trans- ferred to the gas as heat is +2.5 J. How much energy is transferred as heat along (a) path ab and (b) path bc? a b -V Figure 18-43 Problem 50.D) How much work does this engine do ln one cycle? 3- A gas is compressed at a constant pressure of 1.2 Pa from 0.008 m³ to 0.002 m3. In the process, 130 J of energy leaves the gas by heat. (a) What is the work done on the gas? (b) What is the change in its internal energy?As shown in the figure, a chamber with a moveable piston and containing a monatomic ideal gas in an initial state A undergoes an isovolumetric, then an isothermal, and finally an isobaric process to complete the cycle. P (atm) LV (L) When the gas is in the initial state, the volume is 3.00 L, the pressure is 5.00 atm, and the temperature is 200 K. The gas is first warmed at constant volume to a pressure of 4 times the initial value (state B). The gas is then allowed to expand isothermally to some new volume (state C). Finally it is compressed isobarically to its initial state. (Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.)
