Fill in the blanks with appropriate words:
The process of settling of heavier particles is called __________.

Explanation

To fill in the blank, we need to identify the process that describes the settling of heavier particles in a liquid mixture.

1. **Understanding the Concept**: The question asks about a specific process in chemistry where heavier particles in a mixture settle down. This is a common phenomenon in mixtures where solids are suspended in liquids.

2. **Identifying the Process**: The process where heavier particles settle at the bottom of a liquid is known as "sedimentation". This occurs because the heavier particles are affected by gravity, causing them to move downwards.

3. **Final Answer**: Therefore, the complete sentence would be: "The process of settling of heavier particles is called **sedimentation**."
