atmospheric phenomena are all the changes in the atmosphere like

Atmospheric Refraction - Atmospheric refraction is the shift in apparent direction of a celestial object caused by the refraction of light rays as they pass through Earths atmosphere. The twinkling of stars and variation in size of the Sun are due to atmospheric..

In an Earth environment, electromagnetic waves propagate in ways that depend not only on their own properties but also on those of the environment itself. Since the various methods of propagation depend largely on frequency therefore the complete electromagnetic spectrum is now shown for reference..

Introduction - The atmosphere resource of our world is unique and available to our planet only. No other planet is found to have similar atmosphere. Earth's atmosphere is a legacy from history of this planet. It was formed billions of years back. In the formative years..

The standard free energy change is defined as the free energy change for a process at 298 K and 1 atmospheric pressure in which the reactants in their standard states are converted to the products in their standard states. Like the standard enthalpy of ..

It has been seen that energy change occurring during the reaction at constant temperature and constant volume is given by internal energy change. However, most of the reactions in the laboratory are carried out in open beakers or test tubes, etc. In such cases, the reactin..

The calorimeter is kept open to the atmosphere in the determination of change in enthalpy of a reaction. The calorimeter is immersed in an insulated water bath fitted with stirrer and thermometer. The temperature of the bath is recorded in the beginning and after the end o..

Environment of earth includes the whole of atmosphere, hydrosphere as related to biosphere. Therefore, environment includes nature, composition of air, characters of hydrological parameters, sunshine, air pressure, temperature, water resources - their storage and flow and all other physic..

The energy required in breaking one mole of bonds in hydrogen and chlorine molecules are 437 and 244 kJ respectively. It is observed that for the formation of one mole of HCl, 433 kJ of energy is released. Therefore, the energy released during the formation of 2 moles of HCl is 2 x 433 = 866 kJ. Th..
