Final answer:
Filtration, distillation, and crystallization are commonly used separation techniques in daily life.
Step-by-step explanation:
One commonly used separation technique in daily life is filtration. Filtration is a method of physically separating solids from fluids by using a filter medium. For example, when making a cup of coffee, a coffee filter is used to separate the coffee grounds from the liquid coffee.
Another separation technique is distillation. Distillation involves heating a mixture to separate its components based on their different boiling points. An example of distillation is the process of making distilled water from seawater, where the water is boiled and then collected as vapor and condensed back into liquid form.
Crystallization is another physical method of separation commonly seen in daily life. It involves the formation of a solid crystal from a solution by allowing the solvent to evaporate. An example of crystallization is the formation of salt crystals when seawater is left to evaporate in the sun.
