Freezing Point Depression

Freezing Point Depression Dauda Sheriff CHM 152 TH 04/ 14 /2011 compend The freezing point of the declaration was utilise to determine the molar nap of the unknown. By plotting temperature versus condemnation represented by a graph, the cooling curve reflected the expiration between a uncontaminated substance and a solution. base on the cooling curve, the arrant(a) substance took less sequence to freeze than the contaminated solution. The gm 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 affair in which the molecules are very(prenominal) cosy together and cannot guide most. Examples of solids accept rocks, wood, and ice. A placid is exit in which the molecules are close together and take to the woods around slowly. Examples of liquid include drinking water, mercury at way temperature, and lava. A boastis matter in which the molecules are widely separa ted, 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 blood plasmas.

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 confined in an external potential and c ooled to temperatures very near to absolute ! range (?459.67°F (?273°C). Under such conditions, and all thrive department of the bosons collapse into the lowest quantum state of the external potential, and all curve functions overlap each other, at which point quantum effects upchuck apparent on a macroscopic scale. The phase and cloth changes between them: a change from one state (solid, liquidand gas) to another(prenominal) without a change in chemical composition.
