Experiment 9 formal - Lab Report Example Methodology also involves description of procedures like recording of paired values and subsequent calculation of proportionality constants, means and standard deviations. Results section provided tabulated information together with corresponding graphs for the three experiments. This report also contains a discussion section revolving around findings made in the preceding section. Discussion proves whether the hypothetical claim made earlier is true or false. Finally, a conclusion summarizes main concepts of the experiments. Irrespective of their constituent atoms, all gases obey certain relations with environmental parameters of pressure, temperature and volume. Unique relation of gases to these parameters constitutes the three gas laws. This means that gases have similar physical properties, be it CO2, NO2 or H2O (g). While describing behavior of gases in relation to the three physical parameters acknowledged earlier, a forth variable, specifically the number of molecules, is used. The three gas laws explain behavior of gases when two physical parameters are paired. Technically, behavior of gases in relation to any of the three parameters is independent of each other (Myers, 19). In this case, a gas’ behavior with changing temperature can be measured by keeping the pairing variable, either pressure or volume constant. Practically, gases may show slight variation of variable quantities from theoretically expected values. This explains the concept of ideal gas law, a law that combines relationshi p of all the four essential variables of pressure, temperature, volume and the number of moles. Ideal gas law is written as PV = nRT where n = number of moles, P = pressure, T = temperature, V = volume and R = gas constant with a uniform value of 0.0821 L-atm/mole-K. As acknowledged earlier, relationship between two variables can be determined since behavior of each variable in independent of the other variables. In the experiment, the forth
