  • Geothermal Energy
    866 words
    I. Overview of Geothermal Energy Geothermal energy (from the Greek words geo [earth] and therme [heat], thus 'earth heat' energy) is a domestic energy resource with cost, reliability, and environmental advantages over conventional energy sources. Energy from this source comes from the renewable source of heat from deep in the Earth (diagram: A). Heat is brought up to near the surface by thermal conduction (diagram: B) and magma. This heat heats ground water to form hydrothermal resources (natura...
  • Greatest Amount Of The Sun's Heat
    556 words
    Solar Energy This experiment deals with the testing of solar energy and what material holds the greatest amount of heat. Solar energy is heat that the sun gives off. The materials used to determine what holds the heat the longest are rock, soil, water, and stone. The purpose of this project is to see what of the four materials hold the heat the longest. My hypothesis is that soil holds the heat or energy the longest is because soil is black. Black is the number one heat tracker. The procedures I...
  • Heat Energy
    994 words
    Thermodynamics is the branch of science concerned with the nature of heat and its conversion to any form of energy. In thermodynamics, both the thermodynamic system and its environment are considered. A thermodynamic system, in general, is defined by its volume, pressure, temperature, and chemical make-up. In general, the environment will contain heat sources with unlimited heat capacity allowing it to give and receive heat without changing its temperature. Whenever the conditions change, the th...
  • Direct Use And Ground Source Heat Pumps
    3,579 words
    Whether the World Population stabilizes at 8 Billion or 10 Billion, both developing and developed nations will call for increasing amounts of energy as they strive to achieve higher standards of living. The oil crises twenty years ago gave rise to a debate about the availability of energy, adequacy of supply and the hunt for alternatives. Today, there is no shortage of energy, the question is how can we generate and deliver more of it with less environmental impact. Hence, the quest for increase...
  • Heat With Radiation And Conduction
    813 words
    Prediction I predict that the best way to keep coffee warm is to have a silver insulator because of what we know on radiation and silver being a poor emitter compared to a plain beaker or a black one. I predicted this because most saucepans are silver because silver is a poor emitter compared to white and black and also silver is shiny which cuts down heat wasted by radiation. Research After making a cup of coffee it loses heat because of the following factor: . Radiation. Evaporation. Conductio...

  • Direct Use And Ground Source Heat Pumps
    677 words
    GEOTHERMAL ENERGY Geothermal energy is one of the oldest sources of energy. It is simply using and reusing (reusable energy) heat from the inside of the earth. Most of the geothermal energy comes from magma, molten or partially molten rock. Which is why most geothermal resources come from regions where there are active volcanoes. Hot springs, geysers, pools of boiling mud, and fumaroles are the most easily exploited sources. The ancient Romans used hot springs to heat baths and homes, and simila...
  • Hot And Cold Solids
    826 words
    First, you need to know what heat is. Heat is the rattling, wiggling motion of all the atoms that make up a substance. It's a form of motion energy, but special because the solid as a whole isn't going anywhere. How is that possible? Imagine a large crowd of people standing around, in line, perhaps, for concert tickets. They could be standing quietly or shoving and milling about, even though the crowd isn't going anywhere. It's like that with solid objects, which are really vast 'crowds' of indi...
  • Solar Energy Generators
    353 words
    About 47 per cent of the energy that the sun releases to the earth actually reaches the ground. About a third is reflected directly back into space by the atmosphere. The time in which solar energy is available, is also the time we least need it least - daytime. Because the sun's energy cannot be stored for use another time, we need to convert the suns energy into an energy that can be stored. One possible method of storing solar energy is by heating water that can be insulated. The water is hea...
  • Their Stored Energy As Heat
    525 words
    Have you ever wondered how a jet aircraft lifts its tremendous weight off the ground, or what gives a runner the stamina to reach the finish line in a race In order to answer all these questions we must talk about the transformation of one sort of energy into another. The jet aircraft gets its power from jet turbines. These powerful jet engines create a high-pressure stream of very hot gases that push the aircraft forward as they leave the engine. This is an example of heat being transformed int...
  • Use Of Geothermal Power Plants And Resources
    5,101 words
    Geothermal Energy Matt Arnold 9/17/96 Physics 009 Professor A rns The human population is currently using up its fossil fuel supplies at staggering rates. Before long we will be forced to turn somewhere else for energy. There are many possibilities such as hydroelectric energy, nuclear energy, wind energy, solar energy and geothermal energy to name a few. Each one of these choices has its pros and cons. Hydroelectric power tends to upset the ecosystems in rivers and lakes. It affects the fish an...
  • Energy Efficient Building Windows Energy
    3,818 words
    Energy Efficient Building Windows Energy efficient windows have multiple layers of glass. The reason for this is because the more layers of glass you have the better it insulates the house. Three or four layers of glass are one of the best because you have more airspace in between layers. A smaller airspace doesn't insulate the building as well as a thicker airspace would. The thickest an airspace should be is 1 inch because any thicker than that will cause the glass of the window to no longer i...

    Alternative Sources for Energy Millions and millions of barrels of oil, coal, and natural gases are being pumped out of the ground on a daily basis. These fuels are being used to heat homes, run machines, and take people from place to place. It has become a part of everyday living; just as essential as food and water. The more resources that is being pumped, the more people want it. Society has an insatiable thirst for this form of energy that is unyielding. It is a never ending cycle of supply ...
  • Fiber Glass And Mineral Wool Insulation
    637 words
    Before we look at insulation we must see how thermal energy moves. There are three ways it moves. The first is by conduction. Conduction is the transfer of energy by direct contact of particles. Heat spreads through out an object till the object is the same all the way around. (Physical Science section 6.1, page 1) This happens because all particles vibrate unless in an absolute zero situation. These more violently moving particles hit each other. Eventually these particles will vibrate at the s...
  • Poor Conductors Of Heat
    601 words
    Lab #7: Thermal Energy Heat is thermal energy being transferred from one place to another, because of temperature changes. This can take place by three processes. These three processes are known as conduction, convection, and radiation. When we place two objects with different temperatures in contact with each other, the heat from the hotter object will immediately and automatically flow to the colder object. This is known as conduction. Some objects make excellent conductors of heat while other...
  • Loss Of Heat From One Surface
    756 words
    Hypothesis Larger animals lose heat at a lower rate than smaller animals. As the organism gets bigger the volume and surface area ratio decreases. This means that there is less surface area to lose heat from. If we use penguins as an example, the larger penguins live closer to the poles that the smaller penguins. So smaller animals have a higher surface area to volume ration and larger animals are the opposite. As the size of the animal increases the rate f heat loss decreases. The rate of heat ...
