What is the approximate specific latent heat of melting of ice? State why for cooling botiled soft drinks, ice at`0^@C` is better than the same mass of iced-water at `0^@C`

Explanation

### Step-by-Step Solution:

1. **Understanding Specific Latent Heat**:
- The specific latent heat of melting is the amount of heat required to convert a unit mass of a solid into a liquid without a change in temperature. For ice, this value is approximately 336 Joules per gram.

2. **Converting Units**:
- To express this in terms of kilograms, we multiply by 1000 (since 1 kg = 1000 g):
\[
