Computer demo: Conductivity (see C+15+3), runs 5 min.

Computer Demo: Various metal rods are heated and temperatures are graphed. Four metal rods of a set of 6 (Lead, Aluminum,Copper, Brass) are heated at the base with steam. The program graphs the temperature of the tip of each rod on the monitor with a colored trace. Each rod conducts heat at a different rate. The graph takes 5 minutes. Note: German Silver = 46% Cu,34% Zn, and 20% Ni. At Pimentel, a silver rod is used instead of tin. Note: A temperature sensitive paint on each rod changes color from yellow to red with heat.
