Answer:
Scientists who study chemistry, better known as as chemists, spend a great part of their day mixing things. In fact, many people of different ages, backgrounds, and jobs mix things together at some point during their day. For example, we may mix things while in the kitchen, while working outside, or while doing arts and crafts. However, the end result is not always considered a mixture. A mixture is when two or more substances are combined, but each substance keeps its physical properties, which is a characteristic that can be measured or observed. Mixtures do not have a chemical reaction, such as dissolving or burning. Furthermore, a mixture can be reversed, or separated, after being combined.
Explanation:
Let's start with a mixture you might see in a kitchen. Think about how you prepare a salad. You chop up the lettuce, tomatoes, onions, and maybe you throw in a crouton or two. You put them in a bowl and toss. Did anything about the ingredients change? No. Could you separate the salad back into its individual parts? Yes, you could do this easily. A salad is an example of a mixture.
It isn't always easy to separate a mixture, but just because something is difficult doesn't mean that it is impossible. Let's move from the kitchen to the great outdoors. Soil is an example of a mixture. It has many different substances, such as dirt, gravel, and sand. While it would not be an easy task to separate the substances, it could be done using a filter or strainer.
