Give one example where high specific heat capacity of water is used as a heat reservoir.

Explanation

**Step-by-Step Text 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. Water has a high specific heat capacity, meaning it can absorb a lot of heat without a significant change in temperature.

2. **Application in Cold Countries**: In cold climates, maintaining the temperature of liquids like wine and juice is crucial to prevent them from freezing.

3. **Using Water as a Heat Reservoir**: Water can be used as a heat reservoir because it can store a large amount of heat energy. When placed in contact with bottles of wine or juice, the water can transfer heat to these bottles.
