Which one of the following liquids has the highest density?

Options

A. water
B. alcohol
C. mercury
D. kerosene oil

Answer

To determine which of the given liquids has the highest density, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Density**:
- Density is defined as mass per unit volume. The formula for density (ρ) is:
\[ \text{Density} (\rho) = \frac{\text{Mass} (m)}{\text{Volume} (V)} \]

2. **List the Liquids**:
- The liquids given in the question are:
- Water
- Alcohol
- Mercury
- Kerosene

3. **Research the Densities**:
- We need to know the approximate densities of each liquid:
- Density of Water: ~1 g/cm³
- Density of Alcohol (Ethanol): ~0.789 g/cm³
- Density of Mercury: ~13.6 g/cm³
- Density of Kerosene: ~0.81 g/cm³

4. **Compare the Densities**:
- Now, we compare the densities:
- Water: 1 g/cm³
- Alcohol: 0.789 g/cm³
- Mercury: 13.6 g/cm³
- Kerosene: 0.81 g/cm³
- From the comparison, it is clear that mercury has the highest density.

5. **Conclusion**:
- Based on the densities calculated, the liquid with the highest density among the options provided is **Mercury**.

### Final Answer:
- **Mercury** has the highest density among the given liquids.
