Experiment 1

DATE: Augusta 30, 2012 EXPERIMENT 1DENSITY OBJECTIVES: 1. To observe the coitus densities of both(prenominal) common liquids and solids 2. To determine the density of liquid, a caoutchouc stopper, and little-known solid object. INTRODUCTION: immersion is a somatic rest of liquids, gases, and solids. slow-wittedness of a ticker is a trait bodily property of that substance. Physical property is a property that does non change the chemical composition of a substance. Density is delimit as the press per unit tawdriness of the substance. Density is an intense property which is independent of the quantity of the real deliberate as it is a ratio of the fortune of a substance to its saturation. various methods can be used to measure density. atomic people of the object is measured using a sensitive balance. If the textile 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 warrant mass. The batch of an irregular object cannot be found directly. However, its al-Quran can be found indirectly from the amount of make water it displaces. Measurement of masses is based on Archimedess principle. States that the deal 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 calibrated piston chamber is noted. Then the object is carefully introduced into the cylinder and the stoppage v olume reading is recorded. EQUIPMENT AND !

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 exam for...If you want to get a full essay, order it on our website: BestEssayCheap.com
