    In this lab, we tested different experiments on a candle flame in order to better understand properties, combustion, and states of matter. We recorded many observations that could help us reach a conclusion using what we saw happen. When we observed the regular candle flame, we concluded that the heat of the flame vaporizes the liquid wax. Then, we blew this candle out and took a different lit candle into the smoke trail from the burnt out candle. The wax vapor in the smoke is combustible, therefore when introduced to flame, the vapor is burned and it relights the first candle in a fast process. We placed a wire gauze that is fire retardant very close to the candle flame. This seemed to shorten the flame and the smoke went through the holes…

    When flame test research is performed on an element, it is easy to see the color changes just by physically observing it. Often, many elements can have similar emission spectra’s, which is why Kirchhoff invented the Spectrometer. This is a specialized device that uses a prism and two mirrors that allow the light to be conducted into its unique emission spectra. From elements such as lithium to others like selenium, every single element has its own unique color or elemental fingerprint; this is…
