30 g ice at `0”^(@)C` is mixed with 25 g steam at `100”^(@)C`. Find the final temperature and composition

Explanation

To solve the problem of mixing 30 g of ice at 0°C with 25 g of steam at 100°C, we need to follow these steps:

### Step 1: Calculate the heat required to melt the ice
The latent heat of fusion of ice is given as 80 cal/g. To find the heat required to melt 30 g of ice, we use the formula:
\[ Q_1 = m \times L_f \]
Where:
- \( m = 30 \, \text{g} \) (mass of ice)
- \( L_f = 80 \, \text{cal/g} \) (latent heat of fusion)
