Answer
The conversion of liquid to solid requires thermal energy and it is an exothermic process.When water turns into ice, it releases energy. This released energy does not allow other water molecules to turn into ice.This can be done by refrigeration, and water is freezed to ice. Hence, simply placing water in a cup placed in a small ice chest initially at 5 C does not cause the water to freeze.
