What are the examples of decantation, sedimentation, evaporation, winnowing, threshing, seiving?
Answers
Explanation:
Decantation can be used to separate immiscible liquids that have different densities. For example, when a mixture of water and oil is present in a beaker, a distinct layer between the two consistency is formed, with the oil layer floating on top of the water layer.
Examples of Evaporation. Two familiar examples of evaporation are sweating and the rain cycle. ... Water on earth's surface evaporates and travels up through the atmosphere, where it's cooler. The cooler temperatures cause the vapor to condense back into water droplets, which come together to form clouds.
winnow. To winnow is to use an air current on grain in order to blow away chaff, or to separate out the best specimens. When you blow on grains of rice to remove chaff, this is an example of a time when you winnow.
Separating 2 or More Liquids
A common example is decantation of oil and vinegar. When a mixture of the two liquids is allowed to settle, the oil will float on top of the water so the two components may be separated. Kerosene and water can also be separated using decantation.
Sedimentation occurs when the suspended particles are large enough to settle to the bottom of a vessel under their own weight. Tea leaves falling to the bottom in a tea cup, and mud settling to the bottom of a pond, are examples of sedimentation in action.
Answer: For examples; pebbles, broken grains and insects are separated from rice, wheat and pulses; by handpicking. Threshing: Threshing is used for separating seeds from the harvested stalks. Manual Threshing: When the quantity is small, threshing is done manually.
A kitchen strainer with tight wire mesh that strains the pulp out of orange juice is an example of a sieve. A person who doesn't return what he learns is an example of someone who may be described as having a mind like a sieve.
