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 system, how would the results be different?
Assume that the room temperature is 25°C.
OA.
OB.
OC.
The temperatures of the iron bars after 30 minutes would be less than 160°C because heat would be lost to the surroundings.
it would take more than 30 minutes for both iron bars to reach 160°C because heat would be transferred less efficiently.
The temperatures of both iron bars would increase as they absorb heat from the surroundings.
The temperatures of both iron bars
