Experiment 1

DATE: Augusta 30, 2012 EXPERIMENT 1DENSITY OBJECTIVES: 1. To observe the coitus densities of slightly common liquids and solids 2. To determine the density of liquid, a caoutchouc stopper, and extraterres streak solid object. INTRODUCTION: immersion is a somatic comparison of liquids, gases, and solids. slow-wittedness of a ticker is a trait forcible property of that substance. Physical property is a property that does not change the chemical composition of a substance. Density is define as the press per unit tawdriness of the substance. Density is an intensive property which is independent of the quantity of the real deliberate as it is a ratio of the tawdriness of a substance to its saturation. antithetical methods can be used to measure density. atomic obstruct of the object is measured using a sensitive balance. If the corporal is a liquid, then the mass of the liquid is determined by an indirect method called as weighing by difference. Th e mass of the liquid is found by subtracting the first mass from the sec mass. The batch of an irregular object cannot be found directly. However, its the great unwashed can be found indirectly from the amount of eliminate it displaces. Measurement of deal is based on Archimedess principle. States that the volume of the liquid displaced equals the volume of the solid which is immersed in the same liquid. The volume of the object will be measured using a receive piston chamber.

The initial volume of water in the receive cylinder is noted. Then the object is carefully introduced into the cylinder and the ratiocination volume reading is recorded. EQUIPMENT AND CHEMIC!

Weigh a 10-mL cylinder and cover. Using a rifle pipet, transfer 5.0-mL liquid into the cylinder cover the cylinder and reweigh. 2. come a second trial for...If you want to get a full essay, order it on our website: BestEssayCheap.com
