FAQs on NCERT Solutions for Class 6 Science Hindi Chapter 5 Separation of Substances
1. Where can I find accurate, step-by-step NCERT Solutions for Class 6 Science Chapter 5, Separation of Substances?
Vedantu provides detailed, step-by-step NCERT Solutions for Class 6 Science Chapter 5, 'Separation of Substances'. These solutions are prepared by subject experts and follow the latest CBSE 2025-26 syllabus, ensuring every answer is accurate and easy to understand for completing homework and preparing for exams.
2. How should I solve the NCERT question about separating a mixture of sand and water?
To solve this problem as per the NCERT methodology, you should use a combination of two methods. First, allow the mixture to stand undisturbed. The heavier sand particles will settle down at the bottom; this process is called sedimentation. Next, carefully pour the clear water into another container without disturbing the settled sand; this process is called decantation. The NCERT solutions provide clear diagrams to illustrate this two-step process.
3. What is the correct way to answer the textbook question on separating husk from grain using winnowing?
The correct answer involves explaining the principle of winnowing. You should state that this method is used to separate lighter components (husk) from heavier ones (grain) using wind or blowing air. The solution should describe the process: standing on a raised platform and allowing the mixture to fall, where the wind carries the light husk away while the heavy grain falls vertically downwards.
4. The NCERT exercise asks if it's possible to separate sugar from wheat flour. How do the solutions explain the correct method?
Yes, it is possible. The correct method explained in the NCERT solutions is sieving. The answer should state that you use a sieve with fine pores. When the mixture is passed through it, the fine wheat flour passes through the pores, while the larger sugar crystals remain on the sieve, thus separating the two components based on their difference in size.
5. Why is following the step-by-step format in NCERT Solutions crucial for scoring well in exams?
Following a step-by-step format is crucial because it demonstrates a clear understanding of the scientific process. For questions on separation techniques, marks are often awarded for each logical step (e.g., one mark for identifying the correct method like sedimentation, and another for explaining the procedure). This methodical approach, as shown in Vedantu's solutions, ensures you present a complete, logical answer as expected by CBSE evaluators.
6. How do the NCERT Solutions for Chapter 5 help clarify when to use filtration instead of decantation?
While both methods separate an insoluble solid from a liquid, the solutions clarify their specific applications. Decantation is suitable when solid particles are heavy and settle down quickly. However, for separating very fine, suspended particles like in muddy water, filtration is more effective. The solutions explain that filtration uses a filter with extremely fine pores to trap even the smallest solid particles, providing a much clearer liquid.
7. The textbook has a practical question about making 'shikanji'. How do the solutions explain the science behind dissolving sugar before adding ice?
The NCERT solutions explain this using the concept of solubility. A liquid's ability to dissolve a solid (like sugar) decreases as its temperature drops. Therefore, it is easier to dissolve more sugar in water at room temperature. If you add ice first, the water becomes cold, reducing its capacity to dissolve sugar. The solutions correctly advise dissolving the sugar first and then adding ice to cool the shikanji.
8. Do the NCERT Solutions for "Separation of Substances" cover all the questions from the textbook, including the fill-in-the-blanks and true/false?
Yes, the NCERT Solutions for Class 6 Science Chapter 5 are comprehensive. They provide detailed answers for all the exercise questions, including descriptive questions, fill-in-the-blanks, and true/false statements. Each answer is explained to help students understand the underlying concept behind it.
