The purpose of this differential heating lab is to see which of the given materials would heat up faster or remain the same when heated by our heat lamp. in previous years‚ when this lab has been conducted for the most part‚ results were the same as our results. Our background knowledge consisted of knowing about which of the given materials were more flammable. Hypothesis: if differential heating occurs‚ then different materials will heat at different rates. I would assume that the leaves

Abstract: This article deals with the chemical composition of essential oil from the fruits of Solanum erianthum‚ a species extensively used in traditional medicine. The essential oil from fruits was extracted by hydrodistillation and the chemical composition of the essential oil was analyzed by gas chromatography-mass spectrometry (GC-MS). The yield of essential oil based on the dry weight of the plant was 0.05 % (v/w). Twenty two compounds accounting for 99.2 % of the total oil were identified

In this experiment the objective is to separate dyes in washable markers to see how many different dyes are combined to create one color. The technique used to separate the dyes in this experiment is called chromatography. The materials used consisted of – 3 pieces of chromatography paper‚ a tall clear glass‚ water‚ table salt‚ 1 tsp. measuring spoon‚ an 8 oz. measuring cup‚ pencil‚ ruler‚ 6 washable markers‚ and paper towels. The markers used in this experiment have to be water soluble therefore
