Is used for separating a soluble solid from a liquid e.g salt from water.

• Evaporation

• Filtration

• Decantation

• Distillation

Answer explanation

Evaporation is the process used to separate a soluble solid, like salt, from a liquid, such as water, by heating the solution until the liquid evaporates, leaving the solid behind.

Is used for separating an insoluble solid from a liquid e.g. Coffee Filter

• Filtration

• Evaporation

• Distillation

• Decantation

Answer explanation

Filtration is the process used to separate an insoluble solid from a liquid, such as using a coffee filter to separate coffee grounds from brewed coffee. Other methods like evaporation and distillation serve different purposes.

How can we separate sugar and water?

• Evaporate the water

• Add more sugar

• Use a magnet

• Freeze the mixture

Answer explanation

To separate sugar and water, you can evaporate the water. This process removes the water as vapor, leaving the sugar behind. The other options do not effectively separate the two substances.

How can you separate salt from water?

• Evaporation

• Filtration

• Magnetism

• Sedimentation

Answer explanation

Evaporation is the process where water turns into vapor, leaving salt behind. This method effectively separates salt from water, while filtration, magnetism, and sedimentation are not suitable for this purpose.

Which is the best way to separate steel and aluminum?

• Use a magnet

• Use water

• Use a sieve

• Use a chemical reaction

Answer explanation

Steel is ferromagnetic, meaning it is attracted to magnets, while aluminum is not. Therefore, using a magnet is the most effective way to separate steel from aluminum.

Ty placed his cup of water by the windowsill for the day. The next morning, half the water was gone. What happened?

• The water evaporated

• The cup was knocked over

• Someone drank the water

• The water froze

Answer explanation

The water likely evaporated due to exposure to air and sunlight on the windowsill, causing the water level to decrease overnight.

What is the easiest way to separate sand and water?

• Filtration

• Evaporation

• Distillation

• Sedimentation

Answer explanation

Filtration is the easiest method to separate sand and water, as it allows water to pass through a filter while trapping the sand particles. This process effectively separates the two substances quickly and efficiently.

What is one way to separate iron filings and sand?

• Use a magnet

• Dissolve in water

• Use a sieve

• Evaporate the mixture

Answer explanation

One way to separate iron filings and sand is to use a magnet. Iron filings are magnetic and will be attracted to the magnet, allowing you to easily separate them from the non-magnetic sand.

Which of these is an example of a solution?

• Lemonade

• Sand and water

Answer explanation

Lemonade is a homogeneous mixture where the components (water, sugar, lemon juice) are evenly distributed, making it a solution. In contrast, sand and water form a heterogeneous mixture, not a true solution.

A substance or object that allows energy to flow through easily.

• Conductor

• Insulator

• Resistor

• Capacitor

Answer explanation

A conductor is a substance that allows energy, such as electricity or heat, to flow through it easily. In contrast, insulators resist energy flow, resistors limit it, and capacitors store energy.
