Question

question 7 7/10 which of the following is an example of filtration? using a magnet to separate iron separating noodles from water uaing a sieve to separate sand boiling water

Explanation:

• "Using a magnet to separate iron" is magnetic separation, not filtration.
• "Separating noodles from water" can be done by filtration (using a strainer, which acts as a filter to let water pass and retain noodles).
• "Using a sieve to separate sand" is sieving (separating by particle size with a sieve, different from filtration which uses a filter medium to separate solid from liquid).
• "Boiling water" is a physical change (heating to change state), not filtration.

Answer:

B. Separating noodles from water
