Calculate the amount of heat required to raise the temperature of 800 g of iron from `40^(@)C` to `240^(@)C`. Sp. heat capacity of iron `440J//kg^(@)C`.

Explanation

To calculate the amount of heat required to raise the temperature of 800 g of iron from 40°C to 240°C, we can follow these steps:

### Step 1: Convert mass from grams to kilograms
The mass of iron is given as 800 g. To convert this to kilograms, we use the conversion factor:
\[ \text{Mass in kg} = \frac{800 \text{ g}}{1000} = 0.8 \text{ kg} \]
