Khan Academy: Hypotonic, Isotonic, and Hypertonic Solutions (Tonicity)

Hypotonic, isotonic and hypertonic solutions (tonicity). Seeing the effect of various types of solution on the direction of osmosis. [6:29]

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]

Understand suspensions, colloids, and solutions, and learn the difference between molarity and molality. [13:57]

See some common strong acids and strong bases. Also examine some examples of calculating the pH of a nitric acid solution, sodium hydroxide solution, and a calcium hydroxide solution. [12:32]

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]

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...

Video tutorial presents different ways of representing a molecule and gives examples to demonstrate the difference between empirical, structural, and molecular formulas. [6:49]

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

Using PV-diagrams and expansion work to explain parts of the First Law of Thermodynamics. [15:24]

An introductory explanation of the Carnot Cycle and the Carnot Heat Engine. [20:52]
