Given:
An ice chest is filled with 3.5 kg of ice at 0 °C. A second ice chest is filled with 3.5 kg of water at 0 °C.
Find:
Which ice chest is colder and why?
Solution:
Water and ice bot can exists in zero degree C. After several hours the ice chest filled with water is cooler than that of the ice chest filled with ice. Because at 0oc , ice will starts melt. Ice has very significant heat of fusion. Therefore, ice (which must melt before it can go above 0 degrees) must absorb much more heat to increase its temperature than water at 0 degrees.
