# Heat and Thermodynamics

Typical data for experiment H 03. Temperature
distribution along the copper rod for various
times t (in minutes) after application of a
temperature step function to one end.

## H 03: Thermal Conductivity of Metals

###

A solid metal bar is placed in an insulated box. Boundary conditions are
imposed at the ends of the bar by pipes that run hot or cold water into
the box. Ten thermocouples are soldered to the bar so you can plot the
temperature distribution as a function of time. Compare your results
to the solution of the heat equation,

for the boundary conditions you choose.

Optional: Interface the thermocouples to a computer running LabView
for automated data acquisition.
