Question

What role does specific heat play in keeping a watermelon cool for a long time after removing it from a fridge on a hot day?

Answer 1

Watermelon contains 92% of water. Since the specific heat capacity of water is very high 4200 J/(kg K), the specific heat capacity of watermelon is also high. The higher the specific heat of an object the more energy it requires to increase its temperature. So it takes a longer time to heat up, if the surroundings are supplying heat energy at a constant rate. That is why watermelon remains cool for a long time after removing it from a fridge on a hot day.

Answer 2

Answer:

So after removing from the fridge the watermelon remains cool for a long time on a hot day because it requires much heat to raise the temperature. Note:Specific heat is the amount of heat required to raise the temperature of unit mass of substance to unit degree temperature .
