The average degree of freedom per molecule for a gas is 8. The gas performs 30 J of work when it expands at constant pressure. What is the amount of heat absorbed by the gas?
Options:
Answer:
B
Solution:
f = 8 gives CV = 4R and CP = 5R. W = nRΔ T = 30 J. Q = nCPΔ T = 5 × 30 = 150 J (of which Δ U = 120 J). Matches (b).
