A liquid X has specific heat capacity higher than the liquid Y. Which liquid is useful as (i) coolant in car radiators, and (ii) heat reservior to keep juice bottles without freezing ?

Explanation

To solve the question, we need to analyze the properties of the two liquids, X and Y, based on their specific heat capacities.

### Step-by-Step Solution:

1. **Understanding Specific Heat Capacity**:
- Specific heat capacity is the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius. A higher specific heat capacity means the substance can absorb more heat without a significant increase in temperature.

2. **Comparing Liquid X and Liquid Y**:
