Coastal Temperatures – Rankers Physics

Heat Transfer - Conduction and Convection: Practice Problem & Solution

Assertion (A): Temperature near the sea-coast are moderate. Reason (R): Water has a high thermal conductivity.  
Both (A) & (R) are true and the (R) is the correct explanation of the (A)
Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(A) is true but (R) is false
Both (A) and (R) are false

Solution Explained:

To solve this problem, we apply the core principles of Heat Transfer - Conduction and Convection. Understanding the underlying formula is key to arriving at the correct answer below:

Coastal temperatures are moderate because water has a high specific heat capacity, absorbing and releasing large amounts of heat without significant temperature change.

Water's thermal conductivity is not high. Thus, R is false.
