Conceptual Physics Alive: Heat, Temp and Expansion 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, temperature and heat are distinguished from each other. The expansion of solids, liquids, and gases is compared. A discussion on specific heat capacity leads to the physics of a freezing lake. Demonstrations using liquid nitrogen show the effects of low temperatures. Segment length: 44 minutes

Heat, Temp and Expansion Includes:

  • Hewitt begins by comparing internal energy and temperature.
  • Thermometer construction discussed.
  • Celsius and Fahrenheit scales compared.
  • High temperature but low internal energy 4th-of-July-type sparklers.
  • Specific heat capacity.
  • Water's high specific heat, with examples.
  • Aluminum's low specific heat.
  • Specific heat of foods.
  • Example of water's high specific heat: Hot water bottle during Hewitt's childhood on cold Boston winter nights.
  • Global heating via water's high specific heat.
  • Expansion of water upon freezing.
  • Six-sided crystal structure of snowflakes.
  • Why ice is less dense than water.
  • Expansion of water when heated.
  • Graphical explanation of the low density of water at 4°C.
  • No ice on deep lakes in the cold winter.
  • Why ice forms at the surface of a lake in cold weather (with class questions).
  • Demonstration of liquid nitrogen with assistant Ted Brattstrom; balloon volume change; flower going brittle when cooled; cooling cracker and putting in mouth.

Next-Time Question: When a metal ring is heated, will its inner diameter become larger, smaller, or stay the same? (SEE RESOURCES TAB FOR MORE)
