I5-01. Mechanical Equivalent Of Heat - Shot Bag
Purpose
To demonstrate that heat can be produced from mechanical work.
Equipment
Shot bag and digital thermometer.

Description
The temperature of lead shot in a shot bag is measured with the digital thermometer. The shot bag is then beat on the floor about ten times, and the temperature measured once again. The work done in beating the shot bag on the floor has been converted to heat. Not very much heat though: use the tenth degree scale!
