Calorimetry: Practice Problem & Solution

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:

Heat required is given by \(Q = W \cdot c \cdot \Delta T\), where \(W\) is the water equivalent. Here, \(Q = 100\text{ g} \times 1\text{ cal/(g }^\circ\text{C)} \times 1^\circ\text{C} = 100\text{ cal}\) of energy.
