5. (a) During a thermodynamic cycle gas undergoes three different processes beginning at an initial state where p1-1.5 bar, V₁ =2.5 m³ and U₁ =61 kJ. The processes are as follows: (i) Process 1-2: Compression with pV= constant to p2 = 3 bar, U₂ = 710 kJ 3 (ii) Process 2-3: W2-3 = 0, Q2-3= -200 kJ, and (iii) Process 3-1: W3-1 +100 kJ. Determine the heat interactions for processes 1-2 and 3-1 i.e. Q1-2 and Q3-1.
