Calculate heat capacity of 20 kg of water, given that sp. heat capacity of water- `4.2 J//g^(@)C`.

Explanation

To calculate the heat capacity of 20 kg of water, we can follow these steps:

### Step 1: Understand the given data
- Specific heat capacity of water (S) = 4.2 J/g°C
- Mass of water (m) = 20 kg

### Step 2: Convert mass from kilograms to grams
Since the specific heat capacity is given in Joules per gram, we need to convert the mass from kilograms to grams:
