Question

Which of the following techniques can be used to separate a heterogeneous mixture into its component parts? (3 points)

Sort by color
Separation by density
Apply heat
Apply pressure

Answer 1

Sort by color, separation by density, and apply heat are techniques that can be used to separate a heterogeneous mixture into its component parts.

Step-by-step explanation:

Three techniques that can be used to separate a heterogeneous mixture into its component parts are:

1. Sort by color: This involves visually separating the different components of the mixture based on their colors. For example, if a mixture contains red and blue beads, you can separate them by picking out all the red beads and placing them in one container, and all the blue beads in another.
2. Separation by density: This involves using the differences in density of the components to separate them. For example, if a mixture contains sand and water, you can pour the mixture into a container and wait for the sand to settle at the bottom due to its higher density. Then, you can carefully pour off the water, leaving behind the sand.
3. Apply heat: This technique is used when one of the components of the mixture has a significantly lower boiling point than the others. By heating the mixture, you can vaporize the component with the lower boiling point, leaving behind the other components. For example, if a mixture contains water and ethanol, you can heat the mixture to vaporize the ethanol, which has a lower boiling point than water.
