Adhesion And Cohesion

What is adhesion vs. cohesion?

Adhesion is the attraction between different substances, such as water and glass. Cohesion is the attraction between similar substances, like water molecules to each other.

How do adhesion and cohesion affect water behavior?

Adhesion causes water to spread on surfaces, while cohesion pulls water molecules together, forming droplets.

What role do adhesion and cohesion play in capillary action?

Capillary action results from adhesion pulling a liquid up a surface and cohesion helping the liquid stay together as it rises.

Can you explain the effect of cohesion in forming a meniscus?

Cohesion pulls liquid molecules towards each other, creating a curved surface (meniscus) in a container.

Why is adhesion important in everyday life?

Adhesion is crucial for many processes, including paint adherence to walls and effective use of bandages on skin.

What are examples of cohesion in nature?

Cohesion allows insects like water striders to walk on water surfaces without sinking, due to high surface tension.

How do adhesion and cohesion contribute to plant water transport?

These forces allow water to move against gravity through plant xylem from roots to leaves, essential for plant nourishment.

Adhesion and cohesion tell us how substances interact at the molecular level. Adhesion refers to the attractive force between molecules of different substances. It allows substances to cling to different materials while cohesion is the attractive force between molecules of the same substance. It keeps molecules together within the substance. In this article, we will learn the differences between Adhesion And Cohesion in detail.
