Basic Thermodynamic Processes

The word 'thermodynamics' can be divided into two words, 'thermo' and 'dynamics'. The word thermo deals with the heat and thermal phenomenon, whereas dynamics deals with forces or external agent that drives the heat flow or aids in the motion of heat.

Question

1kg air at 600 K and at 150 kPa is contained in a closed cylinder with variable volume. Now, 150 kJ
of heat is added to the air inside the cylinder during an ISOTHERMAL process. Please note that
during this process neither the pressure nor the volume of the air inside the cylinder is not constant.
a) Assuming the air inside the cylinder can be treated as ideal gas please calculate the work done
by the air inside the cylinder onto surrounding.
[b) Sketch the process on a P[kPa] - V[m^3] diagram. Indicate the initial volume of the air and the
direction of the process on the process curve. Please consider that this is a quasi-equilibrium
process.
[c) Sketch the process on a T[K] – V[m^3] diagram. Indicate the direction of the process on the
process curve.
