• It becomes a gas

• It turns into vapor

• It remains unchanged

Which tool is commonly used in the filtering process?

• A magnet

• Filter paper

• A funnel

• A sieve

What is the main purpose of sieving?

• To separate liquids from solids

• To dissolve solids in liquids

• To evaporate liquids

• To separate larger solid particles from smaller ones

How does a magnet help in separating mixtures?

• By dissolving non-magnetic particles

• By attracting magnetic particles

• By filtering solids

• By evaporating liquids

Which industry benefits from using magnets for separation?
