Evaporation is the process of converting liquid water into vapor, typically at the surface, when heat causes water molecules to gain energy and escape into the air as gas.

After sedimentation, decantation is the process of carefully pouring off the clear liquid from the settled solids, effectively separating the water from dust and other particulate matter.

Sedimentation is the process where heavier components in a mixture settle down at the bottom when water or another liquid is added, allowing for separation from the lighter components.

Pebbles and stones are removed from sand through sieving, a process that uses a mesh or screen to separate larger particles from finer materials, ensuring a cleaner, finer sand.

Winnowing is a method used to separate lighter components from heavier ones in a mixture, typically involving grains. This process utilizes wind or air currents to blow away the lighter chaff, leaving the heavier grains behind. It is commonly used in agriculture for cleaning harvested grains, ensuring the removal of husks and debris.

Points are:

• Process: Uses air currents to separate lighter materials from heavier ones.
• Common Use: Primarily used in agriculture for grain cleaning.
• Example: After harvesting, farmers toss the mixture into the air; the wind carries away the lighter chaff, while the heavier grains fall back down.

Threshing is the process used to separate grains from their stalks or husks, typically involving mechanical means or manual methods to detach the edible part from the inedible parts
