Discover other types of pure carbon: fullerenes, nanotubes, and graphene.Free trial of The Great Courses Signature Collection or buyS1 E9 - The Strange Behavior of Water
May 31, 202029minAnalyze one of the weirdest of all substances: water. While we think of water as normal, its boiling, freezing, dissolving, and heat-storing properties are quite extraordinary compared to other molecules. Discover why this is and what water's attributes have to do with the existence of life.Free trial of The Great Courses Signature Collection or buyS1 E10 - Matter in Solution
May 31, 202031minExplore the nature of chemical solutions, which can be liquid, solid, or gaseous, and are ubiquitous in daily life. Examples include dental fillings, air, blood, and soft drinks. Study the components of a solution - the solvent and solute - and the principles of what dissolves what.Free trial of The Great Courses Signature Collection or buyS1 E11 - Interactions: Adhesion and Cohesion
May 31, 202030minProbe the forces that allow lizards to walk up walls: adhesion and cohesion, which are ways that materials interact with themselves and with other materials. By examining these forces in depth, learn how adhesives work and why cotton makes the best towels.Free trial of The Great Courses Signature Collection or buyS1 E12 - Surface Energy: The Interfaces among Us
May 31, 202030minA surface is a discontinuity, or interface, between one phase of matter and another. Focus on this crucial boundary, which affects everything from a spacecraft reentering the atmosphere to the efficient washing of clothes. Explore surface phenomena such as films, surface tension, and catalysts.Free trial of The Great Courses Signature Collection or buyS1 E13 - The Eloquent Chemistry of Carbon Compounds
May 31, 202032minDelve into the richness of organic chemistry - the study of carbon compounds that have links to living things. Learn some of the basic terminology, and survey common organic compounds such as alkanes, alcohols, ethers, aldehydes, ketones, organic acids, and esters.Free trial of The Great Courses Signature Collection or buyS1 E14 - Materials for Body Implants
May 31, 202030minToday, medicine can replace many parts of the human body thanks to an improved understanding of materials and their biochemistry.
