Question

Learning Goal Internal Energy of an ideal gas The internal energy of a system is the energy stored in the system. In an ideal gas, the internal energy includes the kinetic energies (translational and rotational) of all the molecules, and other energies due to the interactions among the molecules. The internal energy is proportional to the Absolute Temperature T and the number of moles n (or the number of molecules N). n monatomic ideal gases, the interactions among the molecules are negligible, and the kinetic energies are only translational. In such cases, the internal energy 3 2 3 3 2 Consider the ideal gas law PV = nRT, the internal energy 2 ▼ Part A- Consider the case where the work the gas does on the pistion (work BY gas) W is Positive. In doing the work (pushing the piston outward), the ideal gas has to consume some of its internal energy. Therefore the ideal gas's internal energy U decreases. Compare the final internal enegy Ufinal to the inital internal energy Uinitial: UinalUinital O Ufinal Uinital
