Answer 1

Answer:

Grain is separated from stalks, while harvesting. Milk or curd is churned to separate the butter . we gin cotton to separate its  seeds from the fibre.Perhaps you might have eaten salted daliya or poha. If you found that it had chillies in it, you may have carefully taken them out before eating.Suppose you are given a basket containing mangoes and guavas and asked to separate them. What would you do? Pick out one kind and place them in a separate container, right? Seems easy, but what if the materials we want to separate are much smaller than mango or guava? Imagine you are given a glass of sand with salt mixed in it. Impossible, even to think of separating salt from this mixture by picking out grains of sand by hand!
