A very hot gas composed of equal numbers of positive and negative ions is in a closed, thermally insulated container and is in thermal equilibrium at temperature . The figure above represents the initial distribution of the ions. A strong uniform electric field directed toward the bottom of the page is now created in and around the container, and the gas is allowed to reach a new thermal equilibrium at temperature . Which of the following best represents a possible distribution of the ions a temperature ?

In a laboratory experiment, students recorded the pressure and volume of a sample of ideal gas as its temperature was varied. The results are represented in the figure above. Which of the following ranks the internal energy of the gas at the labelled points from greatest to least? The horizontal axis is volume V with marked values V-naught, 5V-naught, and 10V-naught, and the vertical axis is pressure with marked values P-naught, 2P-naught, 3P-naught, and 4P-naught. Four labeled points are connected by straight line segments forming a closed shape. Point A at (5V-naught,P-naught) to point B at (V-naught,4P-naught) to point C at (5V-naught,4P-naught) to point D at (10V-naught,2P-naught) and back to point A.
