What you're missing is the latent heat of fusion. You have to put 80 calories into a gram of ice at 0C to change it to liquid water at 0C. Consider what you will not see on a winter morning: The temperature goes above 0C, so the snow all around has to be 0C also, yet the snow does not all melt in one kerpoof! The snow has to wait until the warm air and sun put 80 cal/g in. Also, water in an ice tray doesnot freeze at once. The refrigerator has to work to pull 80 cal/g of heat out of water at 0C to freeze it to ice cubes at 0C.

i think that you would have melted ice at 0 degrees and frozen water at 0 degrees
