Final answer:
The correct option is C.
Salt can be collected from ocean water because it has a higher boiling point than water, allowing for separation by distillation where water evaporates and leaves salt behind, or by crystallization where water evaporates and salt forms crystals.
Step-by-step explanation:
The property that allows salt to be collected from ocean water is based on differences in boiling points, which is a physical property. Considering the given options, the correct choice is C.
Salt has a higher boiling point than water. This difference allows for the separation of salt from water through processes like distillation, where water, being more volatile, boils and evaporates first, leaving the salt behind. Similarly, crystallization can be used where water is evaporated, and the salt naturally crystallizes out.
Saltwater is a homogeneous mixture or a solution consisting of salt (sodium chloride or NaCl) and water (H₂O), where the salt is the solute and the water is the solvent. This mixture cannot be separated into its components by filtration or a semipermeable membrane but can be separated by distillation or crystallization methods.
The complete question is given below:
