A gas expands from I to F in the figure below. The energy added to the gas by heat is 422 J when the gas goes from I to F along the diagonal path. Three paths are plotted on a PV diagram, which has a horizontal axis labeled V (liters), and a vertical axis labeled P (atm). The green path starts at point I (2,4), extends vertically down to point B (2,1), then extends horizontally to point F (4,1). The blue path starts at point I (2,4), and extends down and to the right to end at point F (4,1). The orange path starts at point I (2,4), extends horizontally to the right to point A (4,4), then extends vertically down to end at point F (4,1).

A gas expands from I to F in the figure below. The energy added to the gas by heat is 276 J when the gas goes from I to F along the diagonal path. A pressure-volume graph consists of points and line segments plotted on a coordinate plane, where the horizontal axis is V (liters)and the vertical axis is P (atm). Three points are plotted: point I at (2, 4) point A at (4, 4) point F at (4, 1) Line segments connect the three points to form a triangle. Arrows along the line segments point from I to A, from A to F, and from I to F. (a) What is the change in internal energy of the gas?

If you have 4 moles of a diatomic ideal gas (such as oxygen or nitrogen), how much heat is required to raise the temperature of this gas from 269.5K to 288.3K if the volume of the gas remains constant during the heating? Note: It is understood that your answer is in units of Joules, however do not explicitly include units in your answer. Enter only a number. If you do enter a unit ("J" in this case), you answer will be counted wrong.
If you have 9 moles of a monoatomic ideal gas, how much heat is required to raise the temperature of this gas from 267.3K to 285.8K if the volume of the gas remains constant during the heating? Note: It is understood that your answer is in units of Joules, however do not explicitly include units in your answer. Enter only a number. If you do enter a unit ("J" in this case), you answer will be counted wrong.
