The document summarizes an experimental design lab report that tested how the conductivity of different materials affected the temperature of water. The experiment tested copper, aluminum, plastic and glass and measured the temperature change of water in each material over 20 minutes. The results showed that copper produced the highest temperature change and fastest heat transfer, while plastic produced almost no change, supporting the hypothesis. The conclusion was that materials with smaller specific heat capacity can transfer thermal energy faster.

Supports Hypothesis
Caption: The graph is showing the temperature change of different
materials over 20 minutes for trial 2.
Summary: Copper has the highest temperature change (9.5°C)
and plastic has the lowest change in temperature (0°C).

16. GRAPH
Mean
Caption: The graph is showing the mean temperature change of
different types of conductors over 20 minutes for all trials.
Summary: Copper has the highest temperature change
(8.90°C)and plastic has the lowest change in temperature (0.13°C).

17. GRAPH
Standard Deviation
Caption: The graph shows the standard deviation of the collected
data.
Summary: Copper has the highest Standard Deviation with
0.54°C and both plastic and glass has 0.09°C of standard deviation.

18. ∗ In conclusion, copper would be a better conductor comparing
with aluminum, plastic and glass.
∗ Based on the results of this experiment it can be concluded that
the smaller specific heat capacity, the faster the substance can
transfer thermal energy.
∗ Based on my research, this happened because copper has a
smaller rate of specific heat capacity than other three materials.
∗ The independent variable was conductivity of different materials
and the dependent variable was water’s temperature.
