Please help with the Q2. The table is for Q2

Q1 (a) The work done on an elevated body is due to the weight of a body. Express the potential energy based on abovementioned body with respect to elevation i.e. the distance. (4 marks) (b) Explain isobaric, isochoric and polytropic processes for an ideal gas. When explaining these processes, draw a pressure-volume (P-V) diagram for each process, as well as the path function. (5 marks) (c) Polytropic process of an ideal gas can be expressed either in P-V or T-V relationships. Show that a work which is shown in equation below can be from 8w = PdV (include your assumptions): wv = P.V. [L ()] in 1 (8 marks) (d) Distinguish between above work and the below work, as shown in equations Q1 (e) and Q1 (d) respectively. Note: First, list steps to obtain below work, which can be derived from 8w = s PDV: P2V2 - PV W= 1-n (8 marks) Table Q1(b)(ii) Table B.1 (Continued) 2 cm mol- T./K 337.9 351.4 370.4 390.8 430.6 275 355.4 229 173.
