Barrons Calculus Flashcards
active collection
the use of devices, such as solar panels, to collect, focus, transport, or store solar energy.
barrels
the unit used to describe the volume of fossil fuels.
crude oil
the form petroleum takes when in the ground
energy
the capacity to do work
fission
a nuclear reaction in which an atomic nucleus, especially a heavy nucleus such as an isotope of uranium, splits into fragments, usually two fragments of comparable mass, releasing from 100 million to several hundred million electron volts of energy.
fossil fuel
a hydrocarbon deposit, such as petroleum, coal, or natural gas, derived from living matter of a previous geologic time and used for fuel.
1st Law of Thermodynamics
says that energy can neither be created nor destroyed; it can only be transferred and transformed.
fly ash & boiler residue
waste products produced by the burning of coal.
half-life
the amount of time it takes of a radioactive sample to disappear.
Hubbert Peak (peak oil)
an influential theory that concerns the long-term rate of conventional oil (and other fossil fuel) extraction and depletion. It predicts that future world oil production will soon reach a peak and then rapidly decline.
hydroelectric power
power generated using water. No pollutants, however hydroelectric power requires rivers to be dammed, which constricts the flow of the river and damages habitats. However new habitats in the form of wetlands form
kinetic energy
the energy of motion
nuclear fusion
the process of fusing two nuclei
overburden
the rocks and earth that are removed when strip mining for a commercially valuable mineral resource.
passive solar energy collection
the use of building materials, building placement, and design to passively collect solar energy that can be used to keep a building warm or cool.
petroleum
oil, a hydrocarbon that forms as sediments are buried and pressurized.
photovoltaic cell
a semiconductor device that converts the energy of sunlight into electric energy
potential energy
energy at rest, or stored enrgy
proven reserve
an estimate of the amount of fossil fuel that can be obtained from a reserve
radiant energy
sunlight
scrubbers
devices containing alkaline substances that precipitate out much of the sulfur dioxide from industrial plants air effluent.
2nd Law of Thermodynamics
says that the entropy of the universe is increasing. The concept that, in most energy transformations, a significant fraction of energy is lost to the universe as heat.
strip mining
involves the removal of the earth’s surface all the way down to the level of the mineral seam. Then the overbruden (the top soil that was removed) is replaced , the area is contoured, and then revegetated
