ASSESSMENT

In preparing coffee using the Barako coffee beans, you may pour the boiled coffee mixture into a piece of cloth. Which method is being illustrated?

• Filtration

• Decantation

• Distillation

• Mechanical separation

Which of the following mixtures could NOT be used in separating the components of mixtures through decantation?

• Quail egg in hot water

• Sugar in hot water

• Sand in glass of water

• Utensils in warm water

Which of these methods could be used to separate an insoluble solid from a soluble solids?

• Mixing the mixture with water and then filtering it. Then evaporate the water from the resulting liquid.

• Mixing the mixture with sand and then filtering it. Then evaporate the sand from the resulting solid

• Mixing the mixture with hydrogen gas and then filtering it. Then evaporate the solids out.

• None of the above.

Which method uses the boiling point differences by gradually heated a mixture? The substance that vaporize the easiest will separate first.

• Filtration

• Decantation

• Distillation

• Mechanical separation

A coffee filter is used to separate coffee liquid from ground, this is a suitable example of ____

• filtration

• decantation

• distillation

• mechanical separation

___involves the use of forceps, sieves and other similar tools to separate the components of mixtures.

____is a process that involves the evaporation and condensation of volatile liquids. The more volatile liquid in the mixture boils first, evaporates, then condenses.

____is a method used to separate liquid and a heavy insoluble solid like soil by allowing the solid to settle at the bottom of the container then the liquid above the solid is poured off carefully into another container.

____ is the process of separating the insoluble solid from the liquid substance by allowing the liquid to pass through a porous material called filtering agent.

_____ is the separation of a mixture by passing it in solution or suspension through a medium in which the components move at different rates.
