Which of the following is a homogeneous system ?

Options

A. Muddy water
B. Bread
C. Concrete
D. A solution of suger in water

Answer

To determine which of the following is a homogeneous system, we need to analyze each option based on the definition of a homogeneous system. A homogeneous system is characterized by uniform distribution of its components, meaning that the composition is the same throughout the mixture.

### Step-by-Step Solution:

1. **Understand the Definition of Homogeneous System**:
- A homogeneous system is one where the components are uniformly distributed. This means that if you take a sample from any part of the system, it will have the same composition.

2. **Analyze the First Option: Muddy Water**:
- Muddy water is a suspension where solid particles are dispersed in water. If left undisturbed, the particles will settle at the bottom. This indicates that the particles are not uniformly distributed.
- **Conclusion**: Muddy water is a heterogeneous system.

3. **Analyze the Second Option: Bread**:
- Bread is a type of solid foam, which is a colloid. In colloids, the particles are also not uniformly distributed.
- **Conclusion**: Bread is a heterogeneous system.

4. **Analyze the Third Option: Concrete**:
- Concrete is a mixture of cement, water, and aggregates (like sand and gravel). The components in concrete are not uniformly distributed, as you can see the different materials within it.
- **Conclusion**: Concrete is a heterogeneous system.

5. **Analyze the Fourth Option: Solution of Sugar in Water**:
- When sugar is dissolved in water, it disperses uniformly throughout the solution. The sugar molecules are evenly distributed in the water, making the solution homogeneous.
- **Conclusion**: A solution of sugar in water is a homogeneous system.

6. **Final Decision**:
- Based on the analysis, the only homogeneous system among the options provided is the solution of sugar in water.

### Answer:
The homogeneous system among the options is **Option 4: Solution of Sugar in Water**.
