we already know that PV=nRT then i ve calculated T1

One mole of an ideal gas having CV = 25.0 J.K−1 is in a volume V1 = 28.0 L at P1 = 1.00 bar. It is expanded reversibly along a path given by P = P1 − 0.005000(V − V1) to a final volume V2 = 100.0 L. Calculate the final temperature T2 and the values of q, w, ΔE, ΔH for this change in state.
