If the mass of the gas above is 0.94g‚ calculate its relative molecular mass. [1] Kinetic Theory - Worksheet 4. A gas sample in the laboratory has a volume of 45.9 dm3 at 25.0oC and a pressure of 743Pa. If the temperature is increased to 155oC by compressing the gas to a new volume of 31.0dm3 what is the pressure in atm? 5. There are 135dm3 of gas in a container at a temperature of 26000C. If the gas was cooled until the volume decreased to 75dm3‚ what would the temperature of the gas be? 6. A

MAE219 Review Prof. Y. Ngabonziza 1. The water in a tank is pressurized by air‚ and the pressure is measured by a multifluid manometer as shown in Figure 1. Determine the gage pressure of air in the tank if h1=0.2m‚ h2=0.3m‚ and h3=0.46m. Take the densities of mercury‚ water‚ and oil are given to be 13‚600‚ 1000‚ and 850 kg/m3‚ respectively. 2.

Switch In Ethos During The Iliad we see the warrior ethos as being the main ethos‚ but as we transfer to The Odyssey we see the transformation from warrior ethos to domestic ethos. Furthermore‚ the novel is based on domestic ethos and how home affects the warrior. Throughout The Odyssey we see Odysseus trying to make his way home after the Trojan War. On his adventure home he goes through trials and challenges before he actually makes it home. He has to outsmart people to be able to get where he

alternative approach to understanding the behavior of a gas is to begin with the atomic theory‚ which states that all substances are composed of a large number of very small particles (molecules or atoms). In principle‚ the observable properties of gas (pressure‚ volume‚ temperature) are the consequence of the actions of the molecules making up the gas. The Kinetic Molecular Theory of Gases begins with five postulates that describe the behavior of molecules in a gas. These postulates are based upon some
