Khan Academy: Capillary Action and Why We See a Meniscus

As we get older, we age, our bodies and minds deteriorate, but this isn't true of all species. The video begins with why we age and what biological processes cause aging. Then it covers research on worms, mice, and other animals that...

A video introducing the intermolecular forces in water by exploring capillary action and the formation of a meniscus. Video will discuss the forces of adhesion and cohesion. [8:25]

See how capillary action and the meniscus are related to intermolecular forces in water. [8:26]

Explains how neurons work during the formation and transmission of brain signals.

This video illustrates and explains how seismic waves function. These waves are broken down into two types: surface and body. Take a look into why waves help understand the structure of Earth. [8:38]

What happens when two teens collide? Find out when RJ runs into Chloe in the school hallway! After their collision, they discuss Newton's third law of motion. Their collision is replayed a few times to identify the action and reaction of...

Explore capillary action from different perspectives. In the fourth installment of a nine-part series, scholars perform several experiments to observe capillary action. They look at the meniscus of water in a glass, observe capillary...

A video lecture explaining specific heat, heat of fusion, and the heat of vaporization. See a step-by-step example of how to calculate the amount of heat needed to change the temperature of water. Also explored is the energy required to...

Find out how tonicity is determined by ions that don't move across membranes and how it affects the movement of water. Rishi is a pediatric infectious disease physician and works at Khan Academy. [11:02]

Video lecture explores S-waves and P-waves. [8:38]
