Chemical Engineering Thermodynamics (MCQs)

A gas performs the maximum work, when it expands

  • A. Non-uniformly
  • B. Adiabatically
  • C. Isobarically
  • D. Isothermally
Answer: Option C.

The Isobaric, isothermal and adiabatic process represented in P–V as the following.
Since, area under P−V plot for isobaric process is more than the isothermal and adiabatic process the work done in isobaric process is highest.
