Sea Breeze in Evening – Rankers Physics

Heat Transfer - Conduction and Convection: Practice Problem & Solution

Assertion (A): On the sea shore, cool breeze flows in the evening. Reason (R): Convection currents are set up from sea to the land since land cools slower than water.  
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:

Land heats and cools faster than water. In the evening, land is cooler than the sea. This causes a breeze from land to sea (land breeze), not sea to land. Thus, A is true but R is false.
