Help now 15pts Use the graph to complete the statement below. Assume that pressure and number of moles of gas are constant in this problem. This graph shows that temperature and volume have . A graph of volume versus temperature has temperature in kelvins from 200 to 400 on the horizontal axis, and volume in liters from 0.5 to 1.5 on the vertical axis. 5 points are marked approximately as follows: 225, 0.75; 250, 0.8; 290, 1; 325, 1.1; and 380, 1.3.
