An Ideal Gas, Consisting of N Moles, Undergoes a Reversible

question 1

Multiple Choice

An ideal gas, consisting of n moles, undergoes a reversible isothermal process during which the volume changes from V_i to V_f. The change in entropy of the thermal reservoir in contact with the gas is given by:

• A) nR(V_f - V_i)
• B) nR ln(V_f - V_i)
• C) nR ln(V_i/V_f)
• D) nR ln(V_f/V_i)
• E) none of the above (entropy can't be calculated for an irreversible process)
