4. Clicker Question (slide 1/2)
You transfer equal amounts of heat (1.00 kJ) to two separate samples of 1.00 mol of an ideal monatomic gas each at 25°C. One sample is in a steel tank, and the other is in a container fitted with a frictionless, massless piston. Compare ∆S for each.
∆S for the gas in the steel tank =
a) 1.10 J/K
b) 1.83 J/K
c) 2.97 J/K
d) 3.11 J/K
e) 4.95 J/K
