In cold countries, ethylene glycol is added to water in the radiators of cars during winters. It results in:

Options

A. reducing viscoisty
B. reducing specific heat
C. reducing freezing point
D. reducing boiling point

Answer

To solve the question regarding the addition of ethylene glycol to water in car radiators during winters in cold countries, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Purpose of Ethylene Glycol**:
- Ethylene glycol is a chemical compound commonly used as an antifreeze agent. Its primary function in cold weather is to prevent the freezing of water in car radiators.

2. **Analyzing the Effects of Ethylene Glycol**:
- When ethylene glycol is mixed with water, it alters the physical properties of the solution. One of the most significant effects is the lowering of the freezing point of the mixture.

3. **Identifying the Correct Option**:
- The question provides several options regarding the effects of adding ethylene glycol:
- Option 1: Reducing viscosity
- Option 2: Reducing specific heat
- Option 3: Reducing freezing point
- Among these options, the most relevant effect of adding ethylene glycol is that it reduces the freezing point of the water-ethylene glycol mixture.

4. **Conclusion**:
- Therefore, the correct answer to the question is that adding ethylene glycol to water in car radiators during winters results in reducing the freezing point.

### Final Answer:
The addition of ethylene glycol to water in car radiators during winters results in reducing the freezing point.
