If water had a lower specific heat capacity, would lakes be more likely or less likely to freeze in the winter?
To Find:Whether lakes would be more likely or less likely to freeze in the winter if water had a lower specific heat capacity.
Answer to Problem 51A
Lakes would be more likely to freeze in the winter.
Explanation of Solution
Introduction:
Specific heat is defined as the essential amount of heat for increasing the temperature by 1 unit. Its S.I. unit is
As the specific heat capacity of water is much higher,it requires more heat to change its temperature. Similarly, water needs more time to decrease its temperature.Therefore, it is used as a cooling agent. If the specific heat of the water was less, then a little loss of heat would decrease more temperature.
Conclusion:
Thus, lakes would be more likely to freeze.
