# Calorimeter Study

### Sarah, Alex, Ashlyn, Hayley

Our calorimeter is a pop can, we put insulation and cotton balls around the can for conduction, and we used aluminum foil to surround the insolation for radiation and also aluminum foil to cover the hole for convection.

In our study the one thing we changed for our question was removing the aluminum foil tunnel out from underneath our calorimeter, we kept everything else the same for example the same amount of water and the height.

Will the aluminum tunnel help the heat from the candle travel to the calorimeter to increase the temperature faster?

These graphs are the ones we used with and without the aluminum tunnel under the calorimeter, the one with the higher ending temperature is the one we used with the tunnel, as you can tell the results have showed that the tunnel did help the heat travel to the calorimeter to increase the temperature faster than it did without it.

Graph One.

42-22=20

Heat=100x4.18x20

=8360J

Graph Two.

45-22=23

Heat=100x4.18x23

=9614J

If we were to extend our studies, we would make our aluminum tunnel shorter and move the calorimeter closer down to the heat source. This is because the closer you are the faster the water will heat up and get to a higher temperature.
