Sensation of Warmth and Heat Flow – Rankers Physics

Heat Transfer - Conduction and Convection: Practice Problem & Solution

Assertion (A): When you touch two bodies, the body which is felt warmer must be of higher temperature than the other one. Reason (R): The heat flows from lower temperature to higher temperature.  
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:

Assertion (A) is true; sensation of warmth indicates heat flow to the body from the object. Reason (R) is false; heat always flows from higher to lower temperature. Thus, (A) is true but (R) is false.
