The air inside an oven is at a temPerature of 500 K. A turkey inside the oven is in equilibrium with the air inside the oven. Which of the following is false?
A. There is no heat transfer from the air to the turkey, because there is no driving force for heat transfer.
B. The turkey is not expanding, because there is no driving force for expansion.
C. The moisture in the turkey is not evaporating, because there is no driving force for evaporation.
D. The temperature of the turkey is 500 K at the surface of the turkey, but needn’t be 500 K in the center of the turkey.
E. None of the above statements are false.
A. Incorrect. This statement is true. If the turkey and air are in equilibrium, then there are no driving forces for heat transfer. Try again.
B. Incorrect. This statement is true. If the turkey is at equilibrium with the air, then they are at identical pressures and there is no driving force for expansion. Try again.
C. Incorrect. This statement is true. If the turkey and air are in equilibrium, then there are no driving forces present for chemical reactions or phase changes. Try again.
D. Correct. If we say the turkey is in equilibrium with the air, we are stating that the entire turkey-as-a-system is in equilibrium, outside and inside. If the turkey had a non-uniform temperature, then there would be driving forces for heat transfer within the turkey.
E. Incorrect. One of these statements can be determined to be false. Try again.
