The solar energy use in Africa These days‚ solar energy has been the most talkative alternative energy source in the world. Unlike the gas‚ oil‚ and coal‚ solar enrgy is one of the clean and renewable resource‚ which can not only generate power but also protect the environment. Africa‚ has second largest population‚ estimated 1.6 billion‚ however‚ around one third of it’s people still live in the condition with no eletricity. (Renewable energy in Africa

Laboratory Report: Flame Colors of Metals Abstract The experiment about flame color of metals demonstrates how electrons jump into their excitedstate from their ground state as it came in contact with heat. As it return to its lower energy state‚it emits the absorbed energy in the form of light. A platinum or nichrome wire was dipped into aconcentrated HCL and was heated to clean it. The wire was dipped into different salt solutionsand heated in order to determine the metallic ion’s color and wavelength

ENERGY MANAGEMENT PRINCIPLES INTRODUCTION In the modern days energy has the significant role in our life. With development where we got comfortable life and much modern facilities where we got some problem with excessive use of energy resources as declining of energy sources‚ climate change. So it is an big challenge for present and future generations as the cost of energy increase and its supply decrease‚ older buildings needs to modified and new buildings designed to use less energy. The optimization

and their color from the naked eye appeared as purple‚ which mercury‚ a light blue‚ is very close to in terms of it’s color on the spectrum. For the unknown flame crystals‚ it may NH4+ because the colors that appeared are very similar to the crystals. Next‚ chemicals have to be heated in the flame for the color to emit because heat adds energy to the substance making the electrons more excited‚ allowing for the electrons to transition faster. Then‚ the method of lighting the substance on fire is far
