Filtration and decantation are both methods used to separate solids from liquids, but they work differently. Filtration involves passing the mixture through a filter paper, allowing the liquid to pass through while the solid is left behind. It is used ...

Decantation is preferred over filtration when the solid particles in a liquid have settled at the bottom and the liquid is clear enough to pour off easily. It is a faster and simpler process, especially when the solid is heavy ...
Decantation is a process used to separate liquids from solids or two immiscible liquids (liquids that do not mix) by gently pouring one layer away from the other. For example, after muddy water has settled, the clear water on top ...
Sieving is used at construction sites to separate fine sand from larger pebbles and stones. This process ensures that the sand used in making concrete or plaster is smooth and free of large particles, making the building materials stronger and ...
Sieving is a method used to separate particles of different sizes by passing a mixture through a sieve, which is a tool with small holes. The larger particles remain on top of the sieve, while the smaller particles pass through. ...
Handpicking is used to remove unwanted or harmful items from a mixture by using our hands. This method is especially helpful when the unwanted items are large enough to be easily seen and picked out, like removing pebbles from rice ...
Handpicking is a simple method of separating slightly larger, unwanted materials from useful ones by using our hands. It’s commonly used when the unwanted substances are easy to see and pick out, such as removing stones from grains. This method ...
Sunlight plays a crucial role in the water cycle by providing the energy needed for evaporation. When the sun heats up water in rivers, lakes, and oceans, it turns into water vapor and rises into the atmosphere. Sunlight also helps ...
Dust particles play an important role in cloud formation by providing a surface for water vapor to condense upon. When water vapor rises and cools, it needs something to stick to in order to form droplets. Dust particles in the ...
Water can evaporate on cool days because evaporation depends on the movement of water molecules. Even on cool days, some molecules in the water have enough energy to escape into the air as vapor. The process of evaporation happens as ...
