5. QUESTION

1. You can distinguish on substance from another by several ways. You might observe and measure such properties as color, odor, texture, density, boiling point, and freezing point.

2. Color and density are two physical properties that can help you Identify a substance.

3. Separate substances:
Solids: You can depend on the differences in size, density, solubility, and magnetic properties to separate one solid from another. Filtration helps you separates an insoluble solid from a liquid.
Liquids: You can heat the liquid mixture. When liquid mixture is heated, the liquid with the lower boiling point evaporates will become a vapor, leaving behind the liquid with the higher boiling point. Cooling condenses the vapor back to liquid. Fractional distillation separates substances one by one as the temperature rises.
Gases: You can cool the gas mixture. The gas with higher condensing point will become liquid. The convert it to gas.

4. There are so many other ways to test. Here is two popular ways:
Determine the volume and mass of each substance. Then calculate their densities with the formula. If their densities are different, the substances are not the same. 
You can use some acid. Let the substances react with it. If one doesn't react, or one reacts differently, they are not the same.

5. The process in water-treatment plants generally includes these steps:
First, a chemical is added to the water that causes the larger particles to stick together. They settle to the bottom of the water, where they can be removed.
Next, the water is run through a series of special molecular filters. Each filter removes smaller particles than the one before.
Finally, another chemical, chlorine, is added to disinfect the water and make it safe to drink.
