Answer 1

Explanation:

2 by process of threshing

Answer 2

Explanation:

1. First dissolve the mixture in water. After that it will be observed that only glass particles can be seen. Then use a filter paper to separate glass pieces from water
2. Chaff is the outer cover of grains and hence is lighter than the grain particles.So they can be separated by the process of winnowing.
3. salt and water can be separated by the simple process of evaporation .
4. chalk powder and iron filings are very easy to separate . they can be separated by using a magnet .
5. wheat and sugar can be separated by first dissolving the mixture in water . after the mixture dissolves only wheat is visible . wheat can be separated from water either from filtration or from sedimentation .
6. sand and camphor can be separated by sublimation process since camphor is a sublimable solid whereas sand is not.
7. same as answer 3.
