Silca gel placed in water vapour results in ………… whereas calcium chloride placed in water vapour results in ………….

Explanation

To answer the question regarding the behavior of silica gel and calcium chloride when placed in water vapor, we can break down the solution step by step.

### Step-by-Step Solution:

1. **Understanding Silica Gel**:
- Silica gel is a porous and granular form of silicon dioxide (SiO2). It is commonly used as a desiccant to control humidity.
- When silica gel is placed in water vapor, it adsorbs the moisture from the air. This process is known as adsorption, where molecules adhere to the surface of the solid without being absorbed into the solid.
