Find the amount of heat released if `1kg` steam at `200^(@)C` is convered into `-20^(@)C` ice.

Explanation

To find the amount of heat released when 1 kg of steam at 200°C is converted into ice at -20°C, we need to consider the different stages of the phase change and temperature change involved in this process.

### Step-by-Step Solution:

1. **Cooling Steam from 200°C to 100°C**:
- Here, steam is cooled to its boiling point (100°C).
- The formula for heat released during cooling is:
\[
