Calculating The Collision Diameter And Viscosity Of A Gas

This website was used on October 3, 2014 to help develop a better understanding of collision theory in order to explain the various factors affecting the rate of reaction.

I would guess that the surface area has been decreased and the diffusion distance for gas

Scuba diving is a method of underwater diving in which a diver utilises a Self-Contained Underwater Breathing apparatus (Scuba) to breathe under water. There are three main gas laws that are pertinent to scuba diving. These are Boyle’s Law, Dalton’s Law and Henry’s Law. Throughout this presentation we will examine how gas laws relate to the diving industry and how innovative technology could transform the future of diving.

To use the ideal gas law, the atmospheric pressure was adjusted for due to the lower pressure in the buret when compared to the outer atmospheric pressure. This unequalization of pressures, although corrected, may still be slightly off, thus potentially causing later calculation error when using the ideal gas law to solve for the moles of CO2.

No significant differences between the mean hang times could be found. In the second experiment, the researcher found that helium and nitrogen, gases lighter than air, had longer hang times than air, while carbon dioxide and argon, gases heavier than air, had shorter hang times (see Table 2 and Graph 2). There were significant differences between the mean hang times. Both results were subject to statistical analysis. An ANOVA and a follow-up Tukey HSD test were used on both results in the stat software JMP. In the first experiment, the ANOVA and Tukey HSD test resulted in p-values all over 0.05, which means there were no statistical differences between the mean hang times. In the second experiment, the ANOVA and Tukey HSD test resulted in p-values all under, 0.05, which means there were statistical differences between the mean hang

The purpose of this lab was to determine the effect of temperature on the volume of gas when the pressure is consistent and to verify Charles’ Law. The data from the experiment reveals that as temperature increases, so does volume. This also indicates that as temperature decreases, the volume decreases as well.

Abstract: The objective of the lab is to determine the volumes of the polystyrene spheres with three different measuring tools: Water Displacement, Analytical Scale, and Triple Beam Balance Scale. The experiment is meant to help understand the concept and application of precision and accuracy in experimental measurements. Accuracy is a measure of how closely the results of repeated measurements are to the true value of what is being measured. Precision is the variability in the results from the repeated measurements, and how close the repeated measurements were to one another. In this lab, the method for measuring the volume of the polystyrene spheres is done with the previously stated tools: Water Displacement, Analytical Scale, and Triple Beam Balance Scale. The standard deviation for the entire classes volumes and masses are recorded to determine the densities.

In the fourth stage of this experiment, the density of a gas was determined. A 250ml flask was weighed with an empty rubber balloon and the mass was recorded.

The purpose of this experiment is to investigate some physical and chemical properties of gases and to use these properties to identify these gases when they are encountered.

It was desired to compare a theoretical value of enthalpy of combustion to a literature value. To do this, the theoretical value was calculated using a literature value for the heat of sublimation of naphthalene, the heat of vaporization of water and average bond energies, given in Table 1 of the lab packet.1 Equations (1) and (5) were used to calculate the theoretical enthalpy of combustion of gaseous naphthalene, where n was the number of moles, m was the number of bonds, and ΔH was the average bond energy:

Robert Boyle, a philosopher and theologian, studied the properties of gases in the 17th century. He noticed that gases behave similarly to springs; when compressed or expanded, they tend to ‘spring’ back to their original volume. He published his findings in 1662 in a monograph entitled The Spring of the Air and Its Effects. You will make observations similar to those of Robert Boyle and learn about the relationship between the pressure and volume of an ideal gas.
