In the equation, PVn = constant, if the value of n = 1, then it represents a reversible _____________ process?
Correct answer: A. Isothermal
- A. Isothermal
- B. Isobaric
- C. Polytropic
- D. Adiabatic
Explanation
For an ideal gas, PV = constant means temperature remains constant because PV = nRT. Hence n = 1 in the polytropic equation represents a reversible isothermal process.
