Which process of separating mixtures utilizes the different boiling points of substances?

• A. Distillation
• B. Filtration
• C. Chromatography
• D. Floatation

Answer: (A)

Verified step by step guidance

1. Understand that separating mixtures can be done by exploiting different physical properties of the components, such as boiling point, solubility, particle size, or density.
2. Identify that the process which uses differences in boiling points to separate substances is called distillation.
3. Recall that in distillation, the mixture is heated until one component vaporizes (boils) at its specific boiling point, then the vapor is condensed back into liquid form and collected separately.
4. Compare this with other methods: filtration separates solids from liquids based on particle size; chromatography separates based on affinity to stationary/mobile phases; flotation separates based on density differences.
5. Conclude that since the question asks for the method using different boiling points, the correct process is distillation.
