How does sprinking of salt help in clearing the snow covered roads in hilly areas? Explain the phenomenon involved in the process.

Explanation

To understand how sprinkling salt helps in clearing snow-covered roads in hilly areas, we can break down the explanation into several steps:

### Step 1: Understanding the Components
- **Identify the Components**: The two main components involved in this process are snow (which is essentially frozen water) and salt (a non-volatile solute).

### Step 2: Properties of Salt
- **Non-volatile Solute**: Salt, when added to snow, acts as a non-volatile solute. This means that it does not evaporate and remains in the solution.
