2. (4 pts) A small metal bar, whosetemperature was 20 C at 2 pm was dropped into a container of boiling water. After 10 minutes its temperature rose to 25 C. The metal bar was left in the water until 2:20pm. (a) What was its temperature when it was taken out of the water at 2:20pm? (b) Suppose the bar was then put in in a refrigerator which had a fixed temperature of OC at 2:20pm. At 2:30pm, the temperature...

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 0° C and 100° C, respectively. A small metal bar, whose initial temperature is 100° C, is lowered into container A. After 1 minute the temperature of the bar is 90° C. After 2 minutes (since being lowered into container A) the bar is removed and instantly transferred into the other container. After 1 minute...
