Answer:

Explanation:


Milk is considered a heterogeneous mixture because it consists of multiple components that can be physically separated. Here's a detailed explanation of why option 'B' is the correct answer:

Components of Milk:


Milk is a complex mixture composed of several different substances, including water, fats, proteins, lactose, vitamins, and minerals. Each of these components has different physical properties.

Physical Separation:


One way to determine whether a mixture is homogeneous or heterogeneous is by attempting to physically separate its components. In the case of milk, it is possible to separate its components through physical processes such as:

1. Centrifugation: By subjecting milk to centrifugation, the heavier cream, which contains a higher concentration of fats, can be separated from the lighter liquid portion.

2. Filtration: By passing milk through a filter, larger particles such as curds or impurities can be removed from the liquid portion.

3. Evaporation: By heating milk, the water content can be evaporated, leaving behind solids like fats and proteins.

4. Skimming: Allowing milk to stand undisturbed allows the cream, which contains a higher concentration of fats, to rise to the top, making it possible to separate it from the rest of the milk.

Conclusion:


Based on the ability to physically separate its components, we can conclude that milk is a heterogeneous mixture. The presence of different substances, each with its own physical properties, allows for the separation of these components through various physical processes. Therefore, option 'B' is the correct answer.
