In cold countries, ethylene glycol is used car radiators for both winter as well as summer seasons. Explain.

Explanation

### Step-by-Step Solution:

1. **Understanding Ethylene Glycol**: Ethylene glycol is a chemical compound that is commonly used as an antifreeze in car radiators.

2. **Usage in Winter**: In cold countries, ethylene glycol is particularly useful during the winter season. The primary reason for this is that it has a low freezing point, which means it remains in liquid form even at very low temperatures. This prevents the coolant in the radiator from freezing, ensuring that the engine can operate effectively without any blockages caused by ice.

3. **Usage in Summer**: During the summer season, ethylene glycol is beneficial because it has a high boiling point. This means that it can withstand high temperatures without evaporating. In extreme heat, it remains stable and continues to provide effective cooling to the engine, preventing overheating.
