Two bodies of different temperatures `T_1 and T_2` if brought in thermal contact, do not necessarily settle to the mean temperature `(T_1 + T_2)//2.` Why?

Explanation

To understand why two bodies of different temperatures \( T_1 \) and \( T_2 \) do not necessarily settle to the mean temperature \( \frac{T_1 + T_2}{2} \) when brought into thermal contact, we can analyze the situation using the principles of calorimetry. Here’s a step-by-step solution:

### Step 1: Define the System
We have two bodies:
- Body 1 with temperature \( T_1 \), mass \( m_1 \), and specific heat capacity \( C_1 \).
- Body 2 with temperature \( T_2 \), mass \( m_2 \), and specific heat capacity \( C_2 \).

### Step 2: Establish Heat Transfer
