Here is the answer for your reference:

Answer (i) The 3rd parameter (500) denotes the number of samples or the number of values in the array

Answer (ii) The question is asking the user to plot the Volume vs Pressure plot, as you may have already seen in the video the formulaic relation between Pressure, Volume and Temp is PV = nRT (nR is a constant), from this you can derive the values of Pressure to be P = (nRT) / V , substituting the values of nR and T, we get the resulting formula as 2.0 / V
