How much heat is required to change `10g` ice at `10^(@)C` to steam at `100^(@)C`? Latent heat of fusion and vaporisation for `H_(2)O` are `80 cl g^(-1)` and `540 cal g^(-1)`, respectively. Specific heat of water is `1cal g^(-1)`.

Explanation

To calculate the total heat required to change `10 g` of ice at `0°C` to steam at `100°C`, we will break the process down into three steps:

1. **Melting the ice at `0°C` to water at `0°C`**:
- The heat required for this process is given by the formula:
\[ Q_1 = m \times L_f \]
where:
