Fuels And Note Down The Results
492 wordsScience Investigation AIM: In this investigation we are going to find out which fuel contains the most energy by burning each fuel and using its heat to heat up water. PREDICTION: I predict that Ethanol will contain the most energy. I can backup my answer by referring to my scientific knowledge, Ethanol will burn the quickest because it has more energy stored within its bonds C-C-C. METHOD: In this experiment I will change the fuels, I will use different fuels. I will use 120 ml of water to boil...

Oceans Waters For Energy Conversion
2,731 wordsWhat is Ocean Thermal Energy Conversion? Ocean Thermal Energy Conversion (OTEC) is the process of converting the ocean waters temperature difference at different depths into usable energy. From the solar heated upper depths of the ocean to the cooler depths below 2,000 feet a 40 degree temperature difference must be maintained to generate electricity. This is a relatively new and unheard of source of energy. Many people are not aware of the many benefits of OTEC and the impact it will have in th...

Atmosphere Without Oxygen Early Life
1,074 wordsPlants are critical to other life on this planet because they form the basis of all food webs. Most plants are autotrophic, creating their own food using water, carbon dioxide, and light through a process called photosynthesis. Some of the earliest fossils found have been aged at 3.8 billion years. These fossil deposits show evidence of photosynthesis, so plants, or the plant-like ancestors of plants, have lived on this planet longer that most other groups of organisms. At one time, anything tha...

Electric Energy In The Colombian River Basin
1,501 wordsEnergy Flow Systems Richard White's Organic Machine, and William Cronon's Changes in the Land, both examine environments as energy flow systems. The energy flow model was utilized by the authors to explain relationships within ecosystems. Richard White's thesis is to examine the river as an organic machine, a san energy system that, although modified by human intervention, maintains it's natural, its "unmade" qualities. White emphasizes on energy because it is a useful concept that can be easily...

Hydrothermal Vents Form At Mid Ocean Ridges
623 wordsHydrothermal Vents are considered by scientists to be very unique and complex communities of organisms. The reason for this is due to the fact that unlike most other organisms, Hydrothermal Vents are not powered by the sun's energy. Most organisms on the Earth+s surface depend on plants to produce nutrients from sunlight. This process is called photosynthesis. These communities are unique in that they depend on a different food-making process other than photosynthesis. Bacteria at the vents make...

Development Of Hydroelectric Energy
609 wordsHydroelectricity is the electricity produced by harnessing the power of moving water. Hydroelectric energy is a renewable energy source dependent upon the hydrologic cycle of water, which involves evaporation, precipitation and the flow of water due to gravity. Canada has abundant water resources and a geography that provides many opportunities to produce low-cost energy. In fact, accessing the energy from flowing waters has played an important role in the economic and social development of Cana...

Amount Of Useful Energy
275 wordsSecond 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...

Pressure In The Water Between The Ships
1,172 wordsBernoulli an Thoughts Daniel BernoulliBernoullian Thoughts Essay, Research Paper Daniel Bernoulli was born into a family of mathematicians on February 8, 1700. He was the only person in his family to make an impressive mark on physics. Bernoulli became a Swiss physicist and mathematician who made enormous contributions to the world of physics. He uncovered many significant phenomena in hydrodynamics, and in 1738, published his most famous work, Hydrodynamica, which was a study of equilibrium, pr...
