2. Describe two tests that you can run to determine if something is a substance or a mixture. sc 8.P.8.9

## Step 1: Physical Separation Methods<br />### The first test involves using physical separation methods such as filtration or distillation. If the components can be separated by these methods, it indicates that the material is a mixture.<br />## Step 2: Homogeneous Properties<br />### The second test checks for homogeneous properties throughout the material. If the material has uniform properties in all parts, it is likely a substance.
