Conceptual Physics Alive: Gases

Conceptual Physics Alive: Gases includes a digital video and questions set with answers. Observe Paul Hewitt teach in a classroom with real students, using engaging demonstrations and artwork. In this video, the demonstration-oriented lecture focuses on the atmosphere--its weight, pressure, and the buoyancy it exerts on objects. Barometer, Boyle's Law, and Bernoulli's principle are also discussed. Segment length: 40 minutes Gases Includes: Hewitt demonstrates what happens when an inverted glass is pushed into a container of colored water. The weight of air, and interesting comparisons. Chalkboard sketch of the world and atmosphere, and how air pressure is due to the weight of air. Demonstration of the crushing by the atmosphere of soft drink aluminum cans (first heated with a bit of water in them) inverted one by one into a bath of cool water. Atmospheric pressure. Data on atmospheric pressure with altitude. Demonstration of the burning of a piece of paper in a Jar. Hewitt puts the j
