Heat Transfer - Conduction and Convection: Practice Problem & Solution

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:

Thermal capacity is \(C = mc\), where \(m\) is mass and \(c\) is specific heat. If \(m < 1\) (e.g., in kg), then \(c\) will be numerically greater than \(C\). Thus, (A) is true. (R) states mass can be less than unity, which is true and correctly explains (A).
