Final answer:
Filtration is a method used to separate solids from liquids by passing the mixture through a filter medium. The liquid passes through the filter while the solid particles are retained. For example, filtering a mixture of sand and water will separate the sand particles from the water.
Step-by-step explanation:
Filtration is a method used to separate solids from liquids. It involves passing a mixture through a filter medium, such as filter paper or a porous material, which allows the liquid to pass through while retaining the solid particles. For example, if you have a mixture of sand and water, you can use filtration to separate the sand particles from the water by pouring the mixture through a filter. The water will pass through the filter, while the sand particles will be left behind.
