The average degree of freedom per molecule for a gas is 6. The gas performs 25 J of work when it expands at constant pressure. What is the amount of heat absorbed by the gas?
Options:
Answer:
D
Solution:
f = 6 gives CV = 3R, CP = 4R. At constant pressure W = nRΔ T = 25 J. Q = nCPΔ T = 4 nRΔ T = 4 × 25 = 100 J. Matches (d).
