Capillary Action

The video explores the impact of water on timber, using a matchstick experiment to demonstrate how water causes wood to expand. It explains the molecular structure of water and its polar nature, leading to surface tension and capillary action. These principles are applied to engineering, particularly in boat construction, where wood's properties are used to create watertight structures.

What role does the electronegativity of oxygen play in the behavior of water molecules?

Discuss the significance of the expansion of wood when it absorbs water.

How does the structure of wood contribute to its properties when exposed to water?
