Soaking of water by a sponge is an example of

Options

A. Simple adsorption
B. Physical adsorption
C. Chemisorption
D. Absorption

Explanation

To solve the question "Soaking of water by a sponge is an example of?", we can follow these steps:

### Step 1: Understand the Process
When a sponge comes into contact with water, it absorbs the water. This is a physical process where the sponge takes in the water.

### Step 2: Identify the Type of Interaction
The water molecules are held to the surface of the sponge. This interaction is due to weak forces, specifically Van der Waals forces. These forces allow the sponge to attract and hold onto water molecules.

### Step 3: Define Absorption
Absorption is a process where one substance is taken up by another. In this case, the sponge (the absorbent) takes in water (the absorbed substance).

### Step 4: Conclude the Answer
Since the sponge is absorbing water through weak interactions, we can conclude that soaking of water by a sponge is an example of absorption.

### Final Answer
The correct answer is absorption.
