`1kg` ice at `-10^(@)` is mixed with `1kg` water at `50^(@)C`. The final equilibrium temperature and mixture content.

Explanation

To solve the problem of mixing 1 kg of ice at -10°C with 1 kg of water at 50°C, we will follow these steps:

### Step 1: Calculate the heat released by the water
The heat released by the water as it cools from 50°C to 0°C can be calculated using the formula:
\[ Q_R = m \cdot s \cdot \Delta T \]
where:
