Specific Heat for Melting Ice – Rankers Physics

Calorimetry: Practice Problem & Solution

Assertion (A): Specific heat for melting Ice is infinite. Reason (R): In isothermal process specific heat of substance is infinite.  
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 Calorimetry. Understanding the underlying formula is key to arriving at the correct answer below:

Specific heat is \(C = \frac{Q}{m \Delta T}\). During melting, \(\Delta T = 0\), so \(C\) is infinite. Melting is an isothermal process, so both A and R are true and R explains A.
