Is it advisable to use ethylene glycol in car radiators during summer?

Explanation

### Step-by-Step Solution:

1. **Understanding the Function of Ethylene Glycol**: Ethylene glycol is commonly used in car radiators as a coolant. It serves two main purposes: lowering the freezing point of the coolant mixture and raising the boiling point, which helps in maintaining optimal engine temperatures.

2. **Freezing Point Comparison**: The freezing point of ethylene glycol is significantly lower than that of water. Water freezes at 0°C, while ethylene glycol has a freezing point of around -12°C. This property makes ethylene glycol effective in preventing the coolant from freezing, especially in cold conditions.

3. **Boiling Point Consideration**: In addition to its low freezing point, ethylene glycol also has a higher boiling point than water (approximately 197°C). This means that it can withstand higher temperatures without evaporating, which is beneficial during hot summer months when the engine operates at elevated temperatures.
