In case of compression of one kg of air, the work done will be the least, when the value of polytropic index 'n' is______________________?
Correct answer: A. 1
- A. 1
- B. 1.4
- C. 1.5
- D. Y = Cp/Cv
Explanation
For compression between the same initial and final states, isothermal compression, n = 1, requires the least work because heat is removed continuously and the pressure rises most slowly. The value n = 1.4 represents approximately adiabatic compression of air and therefore requires more work.
