• Hydrogen Energy Atom Levels
    371 words
    Wild Bill's Wild Bohr Quiz Niels Bohr's model of the hydrogen atom, was the primary reason for the understanding of energy levels. Bohr was able to explain the bright line spectrum of hydrogen. Sparked by the recent discovery of the diffraction patterns, scientists believed electrons could be described as waves. Bohr hypothesized that energy is being added to the hydrogen gas in the electricity form, and then leaving the gas in the form of light. He figured the light rays to be quantized, meanin...
  • Solar Energy Cells Sun Passive
    640 words
    Solar Energy The Word solar comes from the Latin word solaris, which means sun. Solar Energy is the act of catching light from the sun and converting it in to energy. This is not new many ancient people used solar energy. The Egyptians, the Greeks, the Romans and American Indians used the sun to warm their homes. There are two types of solar energy, passive and active. If no mechanical devices are used in a solar energy system it is called passive solar energy. This is an appealing energy alter...

    Dark energy what is it? Dark energy is a unknown energy said to take up 70 percent of the universe. The energy is a repulsive gravitational effect that is causing the universe to accelerate out-ward. No one knows exactly what dark energy is or where it comes from. Dark Energy is a new idea. Little is known about dark energy, yet it takes up a huge amount if the universe. Scientist were able to show the universe was expanding at an accelerated rate by measuring the red-shift of an object by comp...

  • Gibb's Free Energy Cycle
    488 words
    The second law of thermodynamics states that energy transitions are imperfect. No matter what, energy is lost. In machines an 75% loss of energy is considered average. In biological reactions there is usually a 60% loss. Since all reactions are constantly losing a percentage of the energy they give, it is necessary to have a constant intake of energy to make up for what is lost. This intake of energy helps life to remain ordered. If something disrupts that order, entropy begins to take effect. ...

    Solar Energy: An Alternative Energy Imagine a perfect source of energy. One with which no pollution what-so-ever is associated with. No poisonous gasses or destruction of rain forests. This abundant source of energy comes from the sun. Solar energy is the visible energy produced in the sun as a result of a constant nuclear fusion reaction that is taking place. The amount of energy at the solar constant, which is at outer edge of the earth's atmosphere, is two calories per minute per cm squared. ...
  • Energy And Us Potential Kinetic Band
    333 words
    Energy Energy is the name given to the ability to do work. Work and energy are measured in the same units. People often confuse energy, power, and force. Force is a push or a pull on an object or body. The amount of work is determined by the strength of the force used and the distance through which it moves. Power measures the rate at which work is done. There are 2 different kinds of energy. Potential energy is often called stored energy. It represents work that has already been done. A rock l...
  • Energy Power Motion Heat
    415 words
    What do we really need, energy or power? This was a question proposed to me at the beginning of the semester and it really made me think. Energy is a property of matter that can be converted into work, heat, or radiation. It is the capacity for doing work, generating heat, and emitting light or radiation. Power is the rate of spending energy or energy per unit time. Immediately, I thought the answer was energy since you need energy to have power. But then I heard that the answer was power and it...
  • Life Expectancy Energy Intensity

    The environmentalist view of the energy intensity is based on the legacy of the I = PAT equation in which environmental Impact equals Population, multiplied by Affluence, and further multiplied by Technology (Earth Report 2000: Revisiting the True State of the Planet. 1999). The further desegregation of this formula implies that energy intensity can be looked upon as an integrative variable describing the impact of both technology and affluence. Bruce et al. (1996) argue that intensity is inver...

    The sun and stars are seemingly inexhaustible sources of energy. That energy is the result of nuclear reactions, in which matter is converted to energy. We have been able to harness that mechanism and regularly use it to generate power. Presently, nuclear energy provides for approximately 16% of the world's electricity. Unlike the stars, the nuclear reactors that we have today work on the principle of nuclear fission. Scientists are working like madmen to make fusion reactors which have the pot...

  • 2 Nd Law Of Thermodynamics Vs E 2
    258 words
    Second Law of Thermodynamics vs. Evolution According to the second law of thermodynamics, when energy is converted from one form to another, the amount of useful energy decreases. In relation to the theory of evolution, this law is not contradictory. The second law of thermodynamics is not relating to energy within living things because living things retain energy from the sun. The sun produces concentrated energy, which increases entropy. To maintain orderly structures, living things use this e...
