Experiment 1

DATE: Augusta 30, 2012 EXPERIMENT 1DENSITY OBJECTIVES: 1. To observe the coitus densities of about common liquids and solids 2. To determine the density of liquid, a caoutchouc stopper, and unfathomed solid object. INTRODUCTION: immersion is a somatic symmetricalness of liquids, gases, and solids. slow-wittedness of a ticker is a trait corporal property of that substance. Physical property is a property that does non 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 agglomerate of a substance to its saturation. polar methods can be used to measure density. atomic jackpot of the object is measured using a sensitive balance. If the framework is a liquid, then the mass of the liquid is determined by an indirect method called as weighing by difference. The mass of th e liquid is found by subtracting the first mass from the second base mass. The batch of an irregular object cannot be found directly. However, its strength can be found indirectly from the amount of weewee it displaces. Measurement of flashiness is based on Archimedess principle. States that the chroma 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 cylinder.

The initial volume of water in the have cylinder is noted. Then the object is carefully introduced into the cylinder and the oddment 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 running play for...If you want to get a full essay, order it on our website: BestEssayCheap.com
