Two containers A and B contain different liquids which are kept at a constant temperature. The temperature of the liquid in containers A and B are 0° C and 100° C, respectively. A metal bar at 100° C is initially put into container A. After one minute, the temperature of the metal drops to 90° C. а. Determine the temperature of the metal after two minutes in container A b. After two minutes, the metal is transferred to container B. One minute later, the temperature of the metal increases by 10° C. Determine the total time required from the start of the process for the metal to reach 95° C.
