Topic: Thermodynamics

If the value of n is infinitely large in a polytropic process PV^n=C, then the process is known as constant

  • A. volume
  • B. pressure
  • C. temperature
  • D. entropy

Answer: A. volume

Explanation: PV^n = C can be written as P^(1/n) * V = C^(1/n). If n is infinity, then 1/n approaches 0, leaving V = Constant (C). This is a constant volume process.
