which physical method can be used for obtaining a sample of salt from a small beaker of salt water?\nboiling\nfreezing\nchromatography\nsorting
Answer
Brief Explanations:
Boiling salt - water causes the water to evaporate as steam, leaving the salt behind as a solid residue. Freezing separates components based on different freezing - points (not applicable here as salt and water don't separate this way for this purpose). Chromatography is used for separating mixtures based on different affinities for a stationary and mobile phase, not for salt - water separation. Sorting is used for separating solid objects by physical characteristics, not for separating a dissolved substance from a liquid.
Answer:
A. boiling
