Introduction Simplest state. 11 Gaseous elements in periodic table: Hydrogen, Helium, Nitrogen, Oxygen, Fluorine, Neon, Clorine, Argon, Krypton, Xenon and Redon 2.Kinetic Molecular Model of Gas (KMT). Five Assumptions for gas particles:  No defined volume but with a defined mass. In other words, their volume is very small as compared to distance in between them. No intermolecular force. No attraction, No repulsion, No potential energy. Total energy=Kinetic energy. Continuous, random motion. Elastic collision. Kinetic Energy proportional to absolute temperature.. 3.Temperature and KMT. . Kinetic Energy proportional to absolute temperature. Temperature increase, Speed increase, Kinetic energy increase. However, it is impossible to define the speed of any one gas particle. As such, the speeds of gases are defined in terms of their root-mean-square speed. .. .. ...

• • 1.Conduction, convection and radiation. 2.Height increases; Temperature decreases 3.Radiative Emission 4. 1.Conduction, convection and radiation. The portion of solar radiation received by the earth is called insolation, meaning "incoming solar radiation".  It is received in the form of short waves, and it warms up the earth’s surface.  The earth in turn gives out or radiates that heat it has absorbed back into the atmosphere in the form of a long wave radiation. This is known as terrestrial radiation The atmosphere allows the rays of the sun to pass through without being heated by them (85%). However, it gets warmed by the terrestrial radiation (85%). So, we see that the air around us does not get heated directly by the sun’s rays but indirectly by the heated surface of the earth through conduction and convention currents. Thus, it is clear that the atmosphere receives a larger part o...

Hotter air stays above. 2.Cooler, Denser air & Hotter, less dense air. -Cooler air is denser. Dense things are heavy. Heavy things stay below. Visa-versa. 3.Air pressure and the density of the air also decrease with altitude. -Temperature is directly proportional to pressure If air pressure increases, the temperature must increase.  If air pressure decreases, the temperature decreases. Up above @stratosphere pressure is less. Less pressure; less temperature. Less temperature; colder air. Because of no air turning over, Stratosphere is still hotter than Troposphere e...

  The effective nuclear charge is always less than the actual nuclear chargedue to ______________ effect. the screening effect or shielding effect We can define the amount of screening of the nuclear charge quantitatively by using a ____________- screening constant, S. Zeff = Z - S . A more accurate approach was developed by John Slater (1900–1976),of Variations in effective nuclear charge for valence electrons( Slater’s rules). Hwever, and we can use his approach if we limit ourselves to elements that do not have electrons in __________ subshells. d or f Electrons for which the principal quantum number n is larger than the value of n for the electron of interest contribute_______ to the value of S. 0 Electrons with the same value of n as the electron of interest contribute_________ to the value of S. 0.35 The value of S for Electrons that have principal quantum...
