Quantative Thermal Conductivity

The Necessary materials we need for this experiment
We the placed an aluminum can filled with water at room temperature and the outside at a much higher temperature.
We Then used the temperature probes to measure the temperature of the aluminum.
 The Graph is a picture of the two temperatures of water between the aluminum can.  We determined that [dQ/dt] is the slope of the heat vs time curve.  This Curve represents heat flow.

For the Slope we obtained a value of 0.8433 J/s. We Believed this to be true because most of the class obtained the same value.

We utilized the heat flow equation to obtain k= 0.02 W/m degree Celsius

Although we were able to find the uncertainty of the area of the can submerged in water, we were unable to obtain the uncertainty for k.  This was because we did not know how to find the uncertainty for  Q. 


In this Immersion heater experiment we calculated the amount of heat elevated through temperature.
The graph has a linear shape because it is the the amount of heat increased in water by every temperature.
The Slope of the line is heat capacity, 0.8372 J/ C
