Snow as an Insulator – Rankers Physics

Heat Transfer - Conduction and Convection: Practice Problem & Solution

Assertion (A): Snow is better insulator than ice. Reason (R): Snow contain air packet and air is bad conductor of heat.  
(1) Both (A) & (R) are true and the (R) is the correct explanation of the (A)
(2) Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(3) (A) is true but (R) is false
(4) 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:

Snow traps air, and air is a very poor conductor of heat. Therefore, snow acts as a better insulator than solid ice. Both assertion and reason are true, and the reason correctly explains the assertion.
