Explanation:
A)
1)A) THRESHING-Threshing is the process of loosening the edible part of grain (or other crop) from the chaff to which it is attached. It is the step in grain preparation after reaping. ... Threshing may be done by beating the grain using a flail on a threshing floor.
WINNOWING-Winnowing is a farming method developed by ancient people for separating grain from chaff. ... In its simplest form it involves throwing the mixture into the air so that the wind blows away the lighter chaff.The heavier grains fall back down for recovery. This method is called
winnowing.
B)SEDIMENTATION-Sedimentation is a physical water treatment process using gravity to remove suspended solids from water. Solid particles entrained by the turbulence of moving water may be removed naturally by sedimentation in the still water of lakes and oceans. ... Sedimentation is the act of depositing sediment.
DECANTATION-Decantation is a process to separate mixtures by removing a liquid layer that is free of a precipitate, or the solids deposited from a solution. The purpose may be to obtain a decant (liquid free from particulates) or to recover the precipitate.
C) EVAPORATION-Evaporation takes place when liquid turns into gas. ... Evaporation comes from the Latin evaporare, which means “disperse in vapor or steam.” Depending on the humidity level of the air around it, any liquid will release some of its molecules into the atmosphere around it. That's evaporation.
CONDENSATION-Condensation is the process by which water vapor in the air is changed into liquid water. In other words, the water in the air, a gas known as water vapor, from your hot shower cooled when it met the surface of the cold mirror. This caused the water vapor to condense, or turn into its liquid form
2) Clear water can be obtained from a sample of muddy water by the method of filtration. In this method, the sample of muddy water is poured through a cloth having fine pores or through a filter paper. Water will pass through the filtering medium, leaving behind the mud.
3)1)The density of materials.
2)The boiling point of materials.
3)State of materials
