Winnowing is the process of separation of grains from husk. This process is done by the action of wind. Filtration is the process of separation of tea leaves from tea. This is the process of separating insoluble solids suspended in a liquid by using a filter. Condensation is the process of conversion of water vapour back in the water. Condensation generally occurs in the atmosphere when warm air rises, cools and looses its capacity to hold water vapour. As a result, excess water vapour condenses to form cloud droplets. Evaporation is the process of separation of salt from seawater. In this process, a liquid converted into its gaseous state. Sedimentation is the process of separation of sand particles from sand and water solution. This method of separation used for the separation of an insoluble solid-liquid mixture.
