f 2 mol of neon (assumed ideal) is heated from 0 °C to 250 °C at a constant pressure of 1 bar, calculate the values of q, w, ∆U, and ∆H. (b) calculate the values of q, w, ∆U, and ∆H for the same neon sample heated to 250 °C at a constant volume from the same initial condition and then isothermally expanded to the same final volume as in part 1. (a).
