Heat Transfer Lab

We utilized a pair of temperature sensors to measure the temperature change and consequently the heat transfer of the differing temperatures between the environments outside and
 inside of the aluminum can as they reached thermal equilibrium.

We determined
dQ/dt by the slope of the Heat vs Time Graph, because it represented the rate at which Heat was changing with respect to time and is consistent with what we defined the heat flow to be. As time progressed the two different temperature approached a thermal equilibrium and did so at the stated rate above.



We concluded k (the thermal conductivity of Aluminum) to be.02 W/m C, by using the dimensions and temperature we stated above, with the equation on the bottom right of the next picture
