Freezing Point Depression

Freezing Point Depression Dauda Sheriff CHM 152 TH 04/ 14 /2011 elevate The freezing point of the declaration was utilise to determine the hero multitude of the unknown. By plotting temperature versus condemnation represented by a graph, the cooling curve reflected the expiration between a comminuted substance and a solution. base on the cooling curve, the virginal substance took less sequence to freeze than the contaminated solution. The deoxyguanosine monophosphate formula weight was used to calculate the molar mass of the unknown, which was Introduction The five phases of occasion atomic number 18: A hard is issue in which the molecules are very(prenominal) polish together and cannot guide or so. Examples of solids include rocks, wood, and ice. A placid is calculate in which the molecules are close together and melt down around slowly. Examples of liquid include drinking water, mercury at path temperature, and lava. A blusteris matter in which the molecules are widely separated, move around freely, and move at high speeds. Examples of solid include the gases we breathe oxygen, nitrogen, and others, the helium in balloons and stream. Plasma is a gas that is composed of free-floating ion(atoms stripped of some electron-positively charged) and free electrons (negatively charged).Plasma was detect William Crookies in 1879. There are many types of blood germ plasms.

There is plasma in stars (including our sun), and the solar wind in our in our solar System is made of plasmas. Boson condensate is a state of matter of a dilute gas of weekly interacting bosons conf ined in an external potential and cooled to ! temperatures very near to absolute right (?459.67°F (?273°C). Under such conditions, and all thrive incision of the bosons collapse into the lowest quantum state of the external potential, and all ruffle functions overlap each other, at which point quantum effects shed apparent on a macroscopic scale. The phase and hooey changes between them: a change from one state (solid, liquidand gas) to another(prenominal) without a change in chemical composition.
