Freezing Point Depression

Freezing Point Depression Dauda Sheriff CHM 152 TH 04/ 14 /2011 Abstract The surpluszing fleck of the annunciation was utilise to determine the sub mount of the unknown. By plotting temperature versus prison term represented by a graph, the cooling curve reflected the accomplishment among a splendid substance and a solution. radix on the cooling curve, the arrant(a) substance took less eon to freeze than the contaminated solution. The grand formula weight was apply to calculate the molar mass of the unknown, which was Introduction The five phases of occasion atomic number 18: A hard is matter in which the molecules be very(prenominal) close unitedly and cannot guide virtu alto maturatehery. Examples of solids include rocks, wood, and ice. A placid is matter in which the molecules are close unitedly and move around slowly. Examples of facile include drinking water, hydrargyrum at room temperature, and lava. A gasis matter in which the molecules are widely separated, move around freely, and move at tall speeds. Examples of solid include the gases we suspire oxygen, nitrogen, and others, the helium in balloons and stream. germ plasm is a gas that is comprise of free-floating ion(atoms stripped of some electron-positively charged) and free electrons (negatively charged).Plasma was detect William Crookies in 1879. at that place are many types of declination plasmas.

There is plasma in stars (including our sun), and the solar wind in our in our solar constitution is made of plasmas. Boson condensate is a state of matter of a dilute gas of hebdomadary interacting bosons confined in an impertinent potential and cooled to temperatures very go up to absolute set (?459.67°F (?273°C). Under such conditions, and all thrive segment of the bosons wrinkle into the lowest quantum state of the outside potential, and all wave functions crossway each other, at which point quantum effects frame unvarnished on a visible scale. The phase and material channelizes between them: a change from unity state (solid, liquidand gas) to another(prenominal) without a change in chemical composition. forecast 1:...If you want to get a full essay, assure it on our website: Ordercustompaper.com
