4. The PV diagram below depicts two equilibrium states (A and B) of two molesof helium gas confined within a piston, which both lie on the same adiabat (a curve whichrepresents a collection of equilibrium states that a system can reach without exchangingheat with its surroundings). You are supplied with a meter stick and a thermometer, so youcan determine the volume of the piston and the temperature of the gas at any stage. Youperform an experiment that takes the system from state B to state A along that adiabat.PP.PaQ=0B(a) Your lab assistant records data on the experiment, but loses track of which statethe recorded quantities belong to, and calls them simply states #1 and #2. Use your labassistant's data below (such as it is) to determine the change of the internal energy of thegas during the process.state #1: temperature = 288 K,state #2: pressure = 2.5 x 104 Pa, volume 0.220 m³(b) Find the work done on or by (specify which) the system during the process. Showyour work and/or explain your reasoning.(c) Suppose the piston was filled with two moles of N₂ instead of helium, and that thestates A and B are the same as before (characterized by the same values of P and V).Explain why the curve joining these states that was an adiabat for helium is not an adiabatfor N₂.

Learning Goal: To understand the ideal gas law and be able to apply it to a wide variety of situations. The absolute temperature T, volume V, and pressure p of a gas sample are related by the ideal gas law, which states that PV = nRT Here n is the number of moles in the gas sample and R is a gas constant that applies to all gases. This empirical law describes gases well only if they are sufficiently dilute and at a sufficiently high temperature that they are not on the verge of condensing. In applying the ideal gas law, p must be the absolute pressure, measured with respect to vacuum and not with respect to atmospheric pressure, and I must be the absolute temperature, measured in kelvins (that is, with respect to absolute zero, defined throughout this tutorial as -273°C). If p is in pascals and V is in cubic meters, use R = 8.3145 J/(mol · K). If p is in atmospheres and V is in liters, use R = 0.08206 L atm/(mol-K) instead.
