The Heat Conduction
Apparatus shows the difference
in the rate of heat conduction
through bars made
of different materials and
through bars of the same
material that have different
cross-sectional areas. The
difference in temperature
between points along each
bar is measured to quantify
the rate of heat conduction.
The Heat Conduction
Apparatus has four metal

one stainless steel, two
brass having different cross-sections). One
end of each bar is heated or cooled by
applying power to the Peltier device which
is attached to one end. Each bar has two 10
kΩ thermistors embedded in it about 3 cm
apart from each other. A cable (male 8-pin
mini-DIN to male 8-pin mini-DIN) is supplied
to connect the thermistors in this apparatus
to the PASPORT Temperature Array
(PS-2157) so data can be recorded from all
eight sensors simultaneously. Foam insulators
are supplied to cover the bars during
the experiment.
The DC Power Supply (PI-9877) powers the Peltier Device and
the thermistors are read by the required Temperature Array
(PS-2157).
Temperature sensors at the end of each type of bar show the
different rates of conduction.
The two temperature sensors in the aluminum bar record
the difference in time of the temperature rise as heat is
conducted through the bar.
