Which of the following processes can be considered as reversible processes? If it doesn't work, explain why? a. The temperature in the refrigerator is exactly - 0.05oC. A room temperature beaker containing water is placed in the refrigerator and left to freeze until it freezes. b. The temperature in the refrigerator is exactly - 0.05oC. A glass beaker containing an ice-water mixture is placed in the refrigerator and left to freeze until it freezes. c. The temperature in the refrigerator is exactly 0.05oC. A beaker containing the ice-water mixture is placed in the refrigerator and left to thaw. d. A diver dives to a depth of 300 m below sea level, P = 31 atm. He quickly rises to the surface, P = 1 atm. e. A diver dives to a depth of 300 m below sea level, P = 31 atm. During water hour, he floats slowly to the surface, P = 1 atm.
