HOMEWORK PROBLEMS REQUIRE USE OF HOMEWORK TEMPLATE. THIS WAS ORIGINALLY POSTED IN WRONG FORUM.
if anyone could answer these questions it would be much appreciated

Q1.
A gas, with mass of 2.3 kg, undergoes a thermodynamic cycle which consists of the following processes,
1→2 Isobaric expansion, =2.3 bar , 1=4.1 m3 and 2=7.9 m3
2→3 Isothermal compression (=constant) where 3=2
3→1 Isometric process where 3−1=20.5 kJkg⁄
First sketch the process and then neglecting ΔK.E. and ΔP.E., determine
a) The work done when the gas undergoes the isobaric expansion, from state 1 to 2: 1→2 .
b) The work done when the gas undergoes the isothermal compression, from state 2 to 3: 2→3 .
c) The heat transfer when the gas undergoes the isobaric expansion, from state 1 to 2: 1→2 .
d) The heat transfer when the gas undergoes the isothermal compression, from state 2 to 3: 2→3.
e) The heat transfer when the gas undergoes the isometric process, from state 3 to 1: 3→1 .
