Select the correct answer. An Iron bar at 200°C Is placed in thermal contact with an Identical Iron bar at 120°C In an Isolated system. After 30 minutes, both Iron bars are at
160°C. If the Iron bars were placed in thermal contact in an open system Instead of an Isolated systemn, how would the results be different?
Assume that the room temperature Is 25°C.
The temperatures of the Iron bars after 30 minutes would be less than 160°C because heat would be lost to the surroundings.
O B. It would take more than 30 minutes for both Iron bars to reach 60°C because heat would be transferred less efficiently.
O c
The temperatures of both Iron bars would Increase as they absorb heat from the surroundings.
O D. The temperatures of both Iron bars would decrease because pleces of them would be ost to the surroundings.
