< < Lecture 16 Lecture 18 > > Resources Cyclohexane at the triple point – The triple point of a substance is the combination of temperature and pressure at which the substance will exist as a solid, liquid, and gas simultaneously. This video shows cyclohexane simultaneously boiling and freezing at Read more…
< < Lecture 13 Lecture 15 > > Resources Why don’t I feel the miles of air above me that are crushing me down? — This article explains why the force of atmospheric pressure (100,000 N per square meter!) doesn’t crush us. Video Transcript Hello there! Welcome to lecture 14: Read more…
< < Lecture 12 Lecture 14 > > PhET Under Pressure Simulation Measure the pressure in a fluid and how it changes with depth, density of the liquid, and gravity. You can also try different container shapes to see what effect it has on pressure. Video Transcript Hello there! Welcome Read more…
< < Lecture 11 Lecture 13 > > PhET Hooke’s Law Simulation Use this simulation to measure the deflection of a spring when a force is applied to it. You can also see what the effects of springs connected in series and in parallel have on the deflection of the Read more…
< < Lecture 10 Lecture 12 > > Resources Gallium induced structural failure of an aluminum baseball bat – Watch as the structure of aluminum is destroyed by gallium atoms that dissolve the aluminum bonds. This is a pretty good indication that matter is atomic; gallium would be unable to Read more…
