Question

Two gases—neon and air—are expanded from P1 to P2 in a closed-system polytropic process with n = 1.2. _____ produces more work when expanded. The gas constants for neon and air are R = 0.4119 and 0.287 kJ/kg·K, respectively.

Answer 1

Answer:

Note that Air requires lesser work

Explanation:

Calculate  for general work done

SInce Gas constant 'R' for:  Neon = 0.4119KJ/kg.k , and Air = 0.287 kJ/kg·K

Calculate for work done of NEON

Calculate for work done of Air
