प्रश्न
Ibrahim collected 10 mL each of fresh water and ocean water. He observed that one sample labeled “P” froze at 0° C while the other “Q” at -1.3° C. Ibrahim forgot which of the two, “P” or “Q” was ocean water. Help him identify which container contains ocean water, giving rationalization for your answer.

उत्तर
Q is ocean water, due to the presence of salts it freezes at lower temperatures (depression in freezing point).
