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...

The state of an ideal gas can be represented by a point on a PV (pressure-volume) diagram. If you know the quantity of gas, n, a unique point in pressure (P) and volume (V) can be used to determine a temperature (T). Each point on a PV diagram also has a single internal energy (U) assigned to it. If a process starts at a point and returns to that same point on a PV diagram, it returns to the same...

One mole of an ideal diatomic gas goes from a to c along the diagonal path in the figure below. The scale of the vertical axis is set by Pab = 4.8 kPa and pc = 2.2 kPa, and the scale of the horizontal axis is set by Vbc-4.4 m3 and Va 2.2 m 3 bc Volume (m) (a) During the transition, what is the change in internal energy of the gas?

D. An ideal gas is contained in a cylinder that is fixed in Ideal gas place. The cylinder is closed by a piston, as shown in the diagram at right. There is no friction between the piston and the cylinder walls. 1. Describe the direction of the force that the piston exerts on the gas. Does your answer depend on whether the piston is moving? 2. How could the piston move so that the work it does on the gas...
