Why are Cp and Cv nearly equal for a solid?
AIts atoms have no kinetic energy
BIts pressure stays at zero
CIts atoms vibrate along one line
DIts volume change is negligible
Answer & Solution
Correct answer: D. Its volume change is negligible
Heating a solid barely changes its volume, so almost no work P ΔV is done and ΔQ ≈ ΔU.
