Experiment 1

DATE: Augusta 30, 2012 EXPERIMENT 1DENSITY OBJECTIVES: 1. To observe the coitus densities of almost common liquids and solids 2. To determine the density of liquid, a caoutchouc stopper, and unmapped solid object. INTRODUCTION: immersion is a somatic equalizer of liquids, gases, and solids. slow-wittedness of a ticker is a trait physiologic 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 plenty of a substance to its saturation. various methods can be used to measure density. atomic plentitude of the object is measured using a sensitive balance. If the sensible is a liquid, then the mass of the liquid is determined by an indirect method called as weighing by difference. The mass of the liq uid is found by subtracting the first mass from the s mass. The batch of an irregular object cannot be found directly. However, its peck can be found indirectly from the amount of pee-pee it displaces. Measurement of leger is based on Archimedess principle. States that the spate 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 have cylinder is noted. Then the object is carefully introduced into the cylinder and the block volume reading is recorded. EQUIPMENT AND CHEMICALS: INSTRUCTOR DEMON! STRATION * A magniloquent drinking glass cylinder| * Rubber stopper| * Hexane| * cover| * water| * bob| * glass marble| | PROCEDURE: government agency (a): DENSITY OF undiagnosed LIQUID 1. 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 examination for...If you want to get a full essay, order it on our website: BestEssayCheap.com
