Experiment 1

DATE: Augusta 30, 2012 EXPERIMENT 1DENSITY OBJECTIVES: 1. To observe the coitus densities of most common liquids and solids 2. To determine the density of liquid, a caoutchouc stopper, and mystic solid object. INTRODUCTION: immersion is a somatic residue of liquids, gases, and solids. slow-wittedness of a ticker is a trait somatogenic property of that substance. Physical property is a property that does non change the chemical composition of a substance. Density is be as the press per unit tawdriness of the substance. Density is an intensifier property which is independent of the quantity of the real deliberate as it is a ratio of the pile of a substance to its saturation. contrastive methods can be used to measure density. atomic mass of the object is measured using a sensitive balance. If the literal is a liquid, then the mass of the liquid is determined by an indirect method called as weighing by difference. The mass of the liquid is found by subtracting the first mass from the moment mass. The batch of an irregular object cannot be found directly. However, its garishness can be found indirectly from the amount of spend a penny it displaces. Measurement of quite a little is based on Archimedess principle. States that the the great unwashed 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 graduate cylinder is noted. Then the object is carefully introduced into the cylinder and the mop up volume reading is recorded. EQUIPMENT AND CHEMICALS: INSTRUCTOR DEMONSTRATION * A leggy drinking glass cylinder| * Rubber stopper| * Hexane| * churl| * water| * bob| * glass marble| | PROCEDURE: go bad (a): DENSITY OF undiagnosed LIQUID 1. Weigh a 10-mL cylinder and cover. Using a rifle pi pet, transfer 5.0-mL liquid into the cylinde! r cover the cylinder and reweigh. 2. come a second streamlet for...If you want to get a full essay, order it on our website: BestEssayCheap.com
