Hint:
We know as much the higher specific heat has a body that much heat requires the body to raise the temperature. Higher the specific heat of a body, the more heat is required to raise the temperature of a body. SO accordingly,
Water has a very high specific heat. Watermelon has a lot of water in it. Due to the presence of water in a watermelon, it has high specific heat.
Step by step solution:
Higher the specific heat capacity of a body, the more heat is required to raise the temperature of a body. So accordingly, Water has a very high specific heat capacity. Watermelon has a lot of water in it. Due to the presence of water in a watermelon, it has high specific heat capacity and therefore thus does not heat up easily. It stays cool.
Watermelon contains almost 92% water since the specific heat of water is too high 4200 J/kg K therefore the specific heat capacity of watermelon is also high i.e, it has a high capacity to absorb heat.
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 .means which substance has higher specific heat that takes that much heat to raise the temperature.
