Thermal Expansion

Thermal expansion is demonstrated by heating a ball, a ring, a copper plate with a hole in it, and a bi-metal strip. A blinker unit from an automobile is demonstrated as an application of thermal expansion of a small bi-metal strip. Equipment: - Ball and ring - Bunsen burner - Beaker of water - Copper plate with hole - Support stand - Drill bit - Propane torch - Wet towel - Bi- metal strip - Bi-metal blinker - 12-V battery - Tail light - Switch ---------------------------- This video is part of the project "Videos of Physics Demonstrations", which is created by Dr. Galli and Dr. Amiri of Physics Department, Weber State University.
