(4 points) q = m × c × Δt Given: q=? m = 34.720g c = 4.18 j/(g x °C) Δt = 41.6°C - 25.2°C = 16.4°C q = (34.720g) (4.18 j/(g x °C) (16.4°C) q = 2380.13j You are trying to figure out the energy change of the water which is the surroundings in the lab. To do that you must take the mass of the metal, which for me was Aluminum, and multiply it by the heat capacity of the water, which was given, then multiply that by the change in temperature, which is the final temperature of the mixture
Fracking is a procedure that has been around as early as 1947. What started as an experiment to obtain more natural gas ended up being a successful operation and has spread worldwide. Natural gas is our number one domestic energy source that fuels basic necessities that we use every day, including; vehicles, heating, cooking, and general electricity. As of 2012, 2.5 million fracking operations have been performed worldwide. Out of those procedures over one million were produced in the United States.
For every ATP that is broken down, it moves 3 sodium ions out and then 2 potassium ions in. This is an example of how energy is used within our bodies. Metabolic processes require energy such as the heart beating, the brain, liver and kidneys. Chemical energy from oxygen and food are converted into useable chemical energy and is converted into heat and work. (401
Approximately one‐third of the millions of gallons of water used in fracking returns to the surface, where it is either reused or trucked to treatment plants. More than half the states allow the open, dirt‐brimmed waste pits that collect toxic fluids to intersect with the water table, even though waste pits are connected to hundreds of cases of water
Hawaii is an ideal location for renewable energy resources. We have the ocean that is a source of hydroelectric power, the winds to power turbines to generate electricity, geothermal energy from the volcanoes, and solar power from the sun. There are about a dozen hydroelectric projects throughout the state of Hawaii – on the Big Island, Maui, and Kauai- generating a total of approximately 30 megawatts of power. Additional hydroelectric power projects are under consideration on Kauai that would produce an estimated 80,000 megawatt-hours of electricity (Star Advertiser, 2012). Wind power projects are also becoming increasingly popular in Hawaii.
Tenkiller is a very large and beautiful man - made lake. Both bodies of water are sources of drinking water to the states they traverse. They both generate hydroelectric power that serves the many cities and states the electricity they need. The Arkansas River is a very large but shallow waterway that has been here long before Arkansas became a state. History records indicate The Arkansas River was home to and owned by Native American Indians, and traveled by many famous explorers.
Final Essay Exam GEOL 108 1. Describe the paths of water through the hydrologic cycle. Explain the processes and the energy gains and losses involved in the changes of water between its 3 states. Operationally, we often most concerned with water does when it reaches the solid earth, both on the surface and in the sub-surface. Explain the relationship between the saturated zone, the water table, a ground water well and the cone of depression, all within the sub-surface.
Inside the hall were engines and generators representing not only the best and newest engineering of America but also of England, Germany, and France (Buers 14). The Palace of Machinery held the power plant that created the 56,000 horsepower needed to sustain the amount of energy used for the Fair. It generated electricity for the lights; as well as ran the massive pumps that fed water to the grounds lagoons and picturesque Cascades. At this point in time only two other power plants in the world had a greater horsepower than the engines featured here. The Allis Chalmers vertical and horizontal refrigerating engine was also here, capable of generating 5,000 horsepower, along with the Curtis Steam Turbine from General Electric Company, which could produce 8,000 horsepower (Corbett 3-5).
It also provides water for 3.5 million acres of cropland. This has increased the agricultural trade for the southwest United States, the water from the river contributes to 15% of the nation’s crops and about 13 percent of its livestock to the tune of more than $1.5 billion a year in agricultural income. Agriculture delivers astonishing benefits for humans and consumes the majority of the Colorado River's water. Diversions from the River for agriculture complete about 78% of the River's
The refinery has devoted many millions of dollars in strategies to control pollution since its creations, yet before the safety regulations of the country were passed. Chevron Richmond refinery was already controlling its pollutant discharges on a conventional treatment system build in the 1960s and 1970s. The first stage of this system uses primary treatment to remove pollutants from water, largely by scanning the oil and hydrocarbons.
