PRESIDENT WILLIAM RUTO VISIT TO CHINA
President William Ruto recently landed in China to engage in high-level discussions focused on economic development and strengthening bilateral ties between Kenya and China. He arrived on September 1, 2024, to participate in the Forum on China-Africa Cooperation (FOCAC), a summit that brings together leaders from various African nations and China.

During his visit, President Ruto is expected to discuss multi-million-dollar agreements with China, especially in infrastructure, trade, and technology.

CAPILLARY ACTION

Can you explain the concept of capillary action?

Capillary action, also known as capillarity, is the ability of a liquid to flow through a narrow space, such as a tube or a porous material, without the need for external pressure or force.
This phenomenon occurs due to the combination of two main factors:

1. *Adhesion*: The attraction between the liquid molecules and the surface of the material they are in contact with. This attraction causes the liquid to "***" the surface.
2. *Cohesion*: The attraction between the liquid molecules themselves, which creates a "skin" on the surface of the liquid that allows it to resist external forces.

When a liquid is placed in a narrow space, such as a capillary tube, the adhesion and cohesion forces work together to cause the liquid to rise up the tube, against gravity. The smaller the diameter of the tube, the greater the effect of capillary action.

Examples of capillary action include:

- Water rising up a paper towel or cloth
- Ink flowing through a pen nib
- Water moving through a plant's roots and stems (xylem)
- ***** flowing through tiny ***** vessels (capillaries)

Capillary action is an important phenomenon in many natural and industrial processes, such as:

- Water purification
- Oil recovery
- Textile manufacturing
- Biomedical applications
