This graph shows six distinct lines. The first line is colored red and is labeled A 8000 Aptek. The second, light green is labeled B 8001 Aptek. The third, dark blue is labeled C 8002 Aptek. The fourth, dark green is labeled D 8000 UNI. The fifth, pink is labeled E 8001 UNI. Finally, the sixth and final line, black is labeled F 8002 UNI. The vertical axis of this graph ranges from zero to2 and represents Internal energy (E plus 3) while the horizontal axis of this graph ranges from zero to 30 and represents Time. All six lines begin at the points of zero on both axes. Lines B and E follow suit, ascending from their starting point to 0.5 on the vertical axis and 6 on the horizontal axis, where they both run across the graph in a near straight line and leave the graph at the points of 0.52 on the vertical and 30 on the horizontal axis. Lines A and D follow suit, ascending from their starting point to 0.25 on the vertical axis and 5 on the horizontal axis, where they both run across the graph in a near straight line and leave the graph at the points of 0.25 on the vertical and 30 on the horizontal axis. Finally, both lines C and F follow suit and rise from their starting point to 1.5 on the vertical axis and 15 on the horizontal axis, where the two lines split, line C rising higher than line F. Line C rises off the graph at the points of 1.75 on the vertical axis and 30 on the horizontal axis while line F rises off the graph at the point of 1.55 on the vertical axis and 30 on the horizontal axis.
