Problem 17DQ
When water is placed in ice-cube trays in a freezer, why doesn’t the water freeze all at once when the temperature has reached 0o C? In fact, the water freezes first in a layer adjacent to the sides of the tray. Why?
Step-by-Step Solution:
Solution 17DQ (i) Step 1: Water at ice cube tray does not freeze all at once. Because the amount of water present in the cube has to release its heat energy into environment so that it can able to freeze completely. The process is not instantaneous. The entire water needs some extra time to completely freeze.
