C HEMISTRY 11L R EPORT T EMPLATE EXPT. Density of Water 4 Introduction The purpose of this report is to determine the effects of temperature on the density of water. The objective of the experiment was to measure the volume of water at various temperatures. Materials and Methods The procedure for this experiment was taken from the University of North Carolina at Chapel Hill Chemistry 101 Lab Manual. Instead of the buret segment being filled with ~5 mL of distilled water, the buret segment was filled with ~5mL of nonane. In addition, instead of the water reaching ~70 ° C, the nonane reached 50 ° C. Also, the temperature did not have to be above 60 ° C to select KEEP to record the current reading from the temperature sensor. Instead of at least
