1The sand in a mixture of sand and water could be separated by _______ the mixture. A. shaking B. melting C. filtering D. freezing

Break Down the Problem

1. Identify the components in the mixture (sand and water).
2. Determine the methods of separation that can effectively separate these components.

Relevant Concepts

• The properties of the components: Sand is a solid and does not dissolve in water, while water is a liquid.

Analysis and Detail

1. Shaking (A): This would not separate the sand from water, as shaking causes the mixture to remain uniform.
2. Melting (B): Melting is a process applicable to solids that turn into liquids. This method doesn’t apply since water is already a liquid, and sand does not melt.
3. Filtering (C): This method utilizes a filter to separate solids from liquids based on particle size. Since sand is larger than water molecules, it will be retained by the filter while water passes through.
4. Freezing (D): Freezing would turn water into ice, but would not effectively separate it from sand.

Verify and Summarize

Among the options, filtering is the only method that effectively separates sand from water due to the difference in their physical states and sizes.

Final Answer

C. filtering
