Q8) (a) The work done during an adiabatic expansion follow the law PVⁿ = C, where C and n are constants, as the volume increases from V₁ to V₂.

The work done can be represented by the shaded area in Fig Q8(a).

An amount of steam expands so as to satisfy the law PV^1.33 = C.

Calculate the work done, in Joules, when the steam expands from a volume of 0.3 m³ at a pressure of 750 kN/m² to a volume of 0.6 m³. (12)
