Calculate the heat required to convert 3 kg of ice at `-12^(@)C` kept in a calorimeter to steam at `100^(@)C` at atmospheric pressure. Given,
specific heat capacity of ice = `2100 J kg^(-1) K^(-1)`
specific heat capicity of water = `4186 J kg^(-1)K^(-1)`
Latent heat of fusion of ice = ` 3.35 xx 10^(5) J kg^(-1)`
and latent heat of steam = ` 2.256 xx 10^(6) J kg^(-1)` .

Explanation

To calculate the total heat required to convert 3 kg of ice at -12°C to steam at 100°C, we will break the process down into several steps:

### Step 1: Heating the Ice from -12°C to 0°C
We need to calculate the heat required to raise the temperature of ice from -12°C to 0°C.

Using the formula:
\[
Q_1 = m \cdot c_{ice} \cdot \Delta T
