An iron bar at 200 degrees celcius is placed in thermal contact with an identical iron bar at 120 degess celcius in an isolated system. After 30 minutes, both iron bars are at 160 degrees celcius. if 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 degrees celcius.
