Demo Title: Frictional Heating

Condition: Good

Principle: Frictional Heating

Area of Study: Thermodynamics

Equipment: 2 X 4, pointed dowels, and 3/8" drill.

Procedure:

Chuck one of the pointed dowels into the drill.  Press into the indentation on the 2 X 4 and start the drill.  Smoke should start to appear within 5 seconds.  If no appreciable smoke appears by then press harder with the drill.

Put a large dull bit into the drill press.  Start drilling into the 2 inch thick piece of iron.  Drill for a few seconds, back off, and immediately fill the drill hole with water.  The water should boil and create appreciable amounts of steam.
