Behaviour of Gases

Chemis attack Lab Report Name : Matric no(prenominal) : championship of experiment : Behaviour of Gases Date of experiment: eleventh June 2012 readers name : Objective To determine the abject boy mass of a vapour. Introduction Gas is 1 of the three classical invokes of matter (the others world tranquil and solid). sound absolute zero, a substance exists as a solid. As heat is added to this substance it melts into a mobile at its melt down point, boils into a fumble at its simmering point, and if het soaring enough would enter a germ plasm state in which the electrons are so energized that they leave their put up atoms from within the assail. A pure throttle may be do up of individual atoms (e.g. a noble triggermanconade or atomic squander standardized neon), elemental molecules do from one type of atom (e.g. oxygen), or compound molecules do from a variety of atoms (e.g. car bon dioxide). A gas potpourri would contain a variety of pure gases much manage the air. What distinguishes a gas from liquids and solids is the vast separation of the individual gas particles. This separation usually makes a colourless gas impalpable to the human observer.

The interaction of gas particles in the presence of take aback and gravitational fields are considered negligible as indicated by the constant velocity vectors. The ideal gas law relates the iv measureable properties of a gas: pressure, volume, number of moles and temperature. In this experiment, the ideal gas law will be used to determine the submarine mass of gases a explosive liquid. A small try ! on of the volatile liquid is placed in a tarred 250 ml Erlenmeyer flaskful. The volatile liquid and flask are heated in simmering water to volatilize the liquid. The air and excess vapour escape, leaving the flask filled only with the volatile liquid vapour at atmospheric pressure and at the temperature of boiling water. The flask is then removed and cooled to condense the vapour. formerly cooled, the flask is weighed. By massing the same flask...If you want to get a skilful essay, order it on our website: BestEssayCheap.com
