Two large containers A and B of the same size are filled with different fluids. The fluids in containers A and B are maintained at circmathrmC and circmathrmC respectively. A small metal bar, whose initial temperature is circmathrmC is lowered into container A After minute the temperature of the bar is circmathrmC After minutes since being lowered into container A the bar is removed and instantly transferred into the other container. After minute in container B the temperature of the bar rises circ How long, measured from the start of the entire process, will it take the bar to reach circmathrmCAssume the final temperature being asked for is reached while the bar is container B
