## determine the heatinteractions Q12 and Q31.5. A gas undergoes a thermodynamic cycle consisting of the following process:i.Process1-2: Constant pressure p1=1.4 bar, V1= 0.028m3,W1-2=10.5kJ,ii.Process2-3: Compression with pV=C, U3=U2 and,iii.Process 3-1: Constant volume, U1-U3= -26.4kJ. There is no significant change in KE

4. A gas undergoes a thermodynamic cycle consisting of three process beginning at an initialstate where p1=1 bar, V1=1.5 m3 and U1=512 kJ. The process are follows:i.Process 1-2: Compression with pv=C to p2=2 bar and U2=690 kJ.ii.Process 2-3: W23=0, Q23= -150kJ andiii.Process 3-1: W31=+50 kJ. Neglecting KE and PE changes, determine the heatinteractions Q12 and Q31.5. A gas undergoes a thermodynamic cycle consisting of the following process:i.Process1-2: Constant pressure p1=1.4 bar, V1= 0.028m3,W1-2=10.5kJ,ii.Process2-3: Compression with pV=C, U3=U2 and,iii.Process 3-1: Constant volume, U1-U3= -26.4kJ. There is no significant change in KE
