Name the liquid which has the highest specific heat capacity.

Options

A. milk
B. gas
C. solid
D. water

Explanation

### Step-by-Step Solution:

1. **Understand the Concept of Specific Heat Capacity**:
- Specific heat capacity is the amount of heat energy required to raise the temperature of a unit mass of a substance by one degree Celsius (or one Kelvin).

2. **Identify Common Liquids**:
- Consider common liquids such as water, alcohol, oil, and mercury.

3. **Research Specific Heat Capacities**:
- Look up the specific heat capacities of these liquids.
- Water has a specific heat capacity of approximately 4.18 J/g°C, which is significantly higher than that of other common liquids.

4. **Conclude the Findings**:
- Based on the data, conclude that water has the highest specific heat capacity among the liquids compared.

5. **State the Answer Clearly**:
- Therefore, the answer to the question is that water has the highest specific heat capacity of any liquid.

### Final Answer:
Water has the highest specific heat capacity of any liquid.
