If a triatomic non-linear ideal gas (vibrations not excited) is heated at constant pressure, what percentage of the heat energy is used to do expansion work?
Options:
Answer:
B
Solution:
Cv = 3R, so Cp = 4R. Fraction as work = (PΔ V)/(qp) = (RΔ T)/(4RΔ T) = 25% (the other 75% raises the internal energy). Matches (b).
