Laboratory Techniques & Measurements Essay

testing ground Techniques & MeasurementsObjectivesBecome familiar with several important science laboratoryoratory techniques. Gain proficiency with some of the common bar devices used in a chemistry laboratory. Determine the raft, caboodle, length, temperature, and density of objects and liquids1. aloofness MeasurementsObjectLength (cm)Length (mm)Pop Can12.0120.0iPhone11.7117.0TV Remote16.3163.02.

Some reasons for the water not boiling at 100C could be different temperature settings, not allowing enough time to fully boil and experimental error.B. 102C-100C 99.2-100100C 1002-0.8100C 1000.02 X100%-0.008X100=2=-0.8C. Height= 3.6, Base=4.21, Width= 1.17Volume = bXh/w4.21X3.6/1.17 = 13.31Density= mass/volume21.3/13.31 = 1.6D. Density= mass/volume19.30=26.15/V-26.15X19.30=V-504.69=VV=504.69ConclusionSome new things that I well-educated from this lab are experimental errors can drastically effect the outcome and adding a substance such as salt to water will increase the density of water. I believe I did wreak the lab objectives because in result of this lab I became familiar with lab techniques, gained experience using lab measuring devices and I learned the volume, mass, length temperature and density of som e objects and liquids.
