1.According to the kinetic theory‚ both the particles in gases and the particles in liquids have kinetic energy. This energy allows the particles in gases and liquids to flow past one another‚ as shown in Figure 13.5. Substances that can flow are referred to as fluids. The ability of gases and liquids to flow allows them to conform to the shape of their containers. Figure 13.5 Both liquids and gases can flow. The liquid on the left is colored water. The gas on the right is bromine vapor. If a

I can infer that as the height in meters increases along with pressure (Pascal’s) the temperature decreases. Calculate the environmental lapse rate (ELR) on the basis of the data given (show all stages of your working and the units involved) (4 marks). The environmental lapse rate (ELR) on the data given is

identify it is to determine its molecular weight. In order to determine the molecular weight of a particular substance which in this experiment’s case is a volatile liquid‚ the need to convert the liquid into a gas arises. The relation among the pressure‚ volume‚ temperature and the number of moles of a gas will be an important key in the conclusion of its molecular weight. However‚ in the process of vaporization‚ there is a possibility that some of the vaporized liquid will escape the flask and

Climates and Oceans- 1. With coastal climates‚ the locations are on the windward side‚ meaning the weather patterns move from the ocean to land‚ giving them mild summers and cool winters. This means that there isn’t a very large temperature range for coastal climates. Inland climates are more of the land heating and cooling‚ because they heat to high temperatures in the day and then cool a great amount at night. Also‚ the weather patterns are moving from land to water‚ creating warmer summers and

hs = hf So : Pf/ρ + Vf/2 = Ps/ρ + Vs2/2 So as the velocity increases‚ the formula suggests that the pressure decreases. Since the velocity above the fan is larger than the velocity around it‚ the pressure around the fan is larger than the pressure above the fan. The net force F = ΔP.A that acts on the ball is from the high pressure area(surrounding) to the low pressure area(above the fan) which makes the ball return to its initial position. Recorded air velocity = 5.4 +/- 0.5
