Additional Details

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 jar on his forehead and it sticks.
  • Demonstration of atmospheric pressure with a toilet plunger.
  • Demonstration of atmospheric pressure with a sheet of rubber.
  • Demonstration of a filled glass of water covered with a piece of cardboard and held above the head.
  • Mercury barometer explained.
  • Demonstration of air poured from one container to another beneath the surface of water.
  • Explanation of caissons tor underwater construction.
  • Boyle's law.
  • Review of the weighted balloon that barely floats (from the previous lecture).
  • Snorkeling and scuba diving.
  • Bernoulli's principle.
  • Demonstration of various balls suspended in the air by an air stream.
  • Airplane lift.
