Answer

Explanation:

Step1: Analyze question 1

Wood beads and clay beads can be separated by density as they may have different densities and can be separated using methods like flotation.

Step2: Analyze question 2

Sugar is soluble in water. Evaporating water from a sugar - water mixture (boiling the mixture) will separate the sugar as the water evaporates and the sugar remains.

Step3: Analyze question 3

Salt is soluble in water, iron filings are magnetic. These two properties (solubility and magnetism) can be used to separate salt, pepper and iron filings.

Step4: Analyze question 4

According to the law of conservation of mass, when salt is dissolved in water and the water is evaporated, the mass of the salt remains the same as no chemical reaction occurs to change the amount of salt.

Answer:

  1. B. Density
  2. H. 3
  3. A. Solubility and magnetism
  4. G. 100 g, because the mass of the salt remains the same
