Heat required to increases the temperature of `1kg` water by `20^(@)C`

Explanation

To find the heat required to increase the temperature of 1 kg of water by 20°C, we can use the formula for heat transfer:

### Step 1: Write down the formula for heat transfer
The formula for calculating the heat required (ΔQ) is:
\[ \Delta Q = m \cdot s \cdot \Delta T \]
where:
