- A monatomic ideal gas is initially in state A. The gas undergoes a transition from state A by the three different processes shown, where process III is isothermal. In which process is energy added to the gas by heating? Explain briefly.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.A student is asked to sketch a pV diagram for a gas that goes through a cycle consisting of (a) an isobaric expansion, (b) a constant-volume reduction in temperature, and (c) an isothermal process that returns the gas to its initial state. The student draws the diagram shown in the figure. What, if anything, is wrong with the student's diagram?

- 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.You have two identical containers, each filled with 1 mol of an ideal gas at identical temperature - one is filled with Ne, the other is filled with H2 . Assume atomic mass of Ne > atomic mass of H2a) You increase the temperature of both containers by the same value. Do you need the same / more / less energy to increase the temperature of the Ne compared to H2 ? Argue and explain.b) How does the average speed of gas atoms / gas molecules in both containers compare to each other? Do the gases have the same speed in both containers or does one gas move faster or slower than the other? Argue and explain.An ideal gas goes from state (pi, Vi ) to state (pf, Vf ) when it is allowed to expand freely. Is it possible to represent the actual process on a PV diagram.explain?

Explain briefly.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.
