Methods of Separating Solid from Liquid
Which of these are methods of separating a solid from a liquid?
A) sedimentation, decantation and filtration B) decantation, filtration and evaporation C) decantation, winnowing, threshing D) sedimentation, dissolving, condensation
Final answer:The correct option is (B) decantation, filtration and evaporation
Among the options given, decantation, filtration, and evaporation are the methods used for separating a solid from a liquid.
Answer:
Option B: decantation, filtration, and evaporation are indeed methods of separating a solid from a liquid.
Decantation involves pouring off a liquid to leave behind a solid residue, filtration uses a porous barrier to separate a solid from a liquid, and evaporation entails heating a liquid until it turns into a gas leaving the solid behind.
The methods for separating a solid from a liquid range and can be determined based upon the properties of the substances involved. Among the options given, decantation, filtration, and evaporation are effective methods for this purpose.
Decantation involves carefully pouring off the liquid while leaving the solid particles settled at the bottom. Filtration makes use of a barrier that allows the liquid to pass through while trapping the solid particles. Evaporation involves heating the liquid to the point where it changes to a gas, leaving the solid behind.
These methods are crucial in various industries such as the chemical, pharmaceutical, and environmental sectors. Understanding how to separate solids from liquids is essential for processing raw materials, purifying substances, and ensuring environmental safety.
By employing decantation, filtration, and evaporation, scientists and engineers can effectively separate solids from liquids to achieve specific goals and maintain high standards of quality and safety.
