question 7

1. which physical property helps separate the raisins out of a bag of trail mix?

hand separation
filtration
chromatography
magnetism

Explanation:

To solve this, we analyze each option:

• Hand separation: Trail mix components (like raisins, nuts, cereal) are different sizes/shapes, so we can pick raisins by hand.
• Filtration: Used for separating solids from liquids (e.g., sand from water), not solid - solid in trail mix.
• Chromatography: Separates mixtures based on solubility/movement (e.g., ink dyes), not for trail mix.
• Magnetism: Separates magnetic materials (e.g., iron filings), raisins aren’t magnetic.

So hand separation is the correct method.

Answer:

A. Hand separation
