Demos: 1M-06 Mechanical Equivalent of Heat (Shot Drop)

A mass of copper shot is securely corked in a long clear plastic tube (2 meters long). Before starting this demonstration, insert the thermocouple into the tube and record the temperature of the shot. Keep the thermocouple in the tube until equilibrium is reached. Note the temperature and remove the thermocouple. Take the tube and invert it rapidly so that the shot rushes from one end of the tube to the other. Please invert it quickly so that the shot will fall and not roll along the sides of the tube. Keep track of the n number of inversions that are made and that will be the equivalent to the shot falling 2n meters. When finished, insert the thermocouple and notice the change in temperature.
