TK Exploring Energy

TK 3.1 Exploring Energy Vocab

QuestionAnswer
Biomass Plant materials and animal waste used especially as a source of fuel.
BTU (British Thermal Unit) The heat equal to 1/180 of the heat required to raise the temperature of one pound of water from 32 degrees Fahrenheit to 212 degrees Fahrenheit at a constant pressure of one atmosphere.
Chemical Energy The potential energy locked within a system and released during a chemical reaction.
Climate Change Any significant change in measures of climate, such as temperature, precipitation, or wind, lasting for an extended period of a decade or longer.
Conservation The process of controlling resources; for example, limiting soil erosion, reducing sediment in waterways, conserving water, and improving water quality.
Efficiency The ratio of the useful energy delivered by a dynamic system to the energy supplied to it.
Electrical Energy Energy associated with the flow of electrons.
Electricity The flow of electrical power or charge.
Energy The ability to do work; types include heat, light, sound, chemical, nuclear, mechanical, electrical.
Environment External surroundings.
Exhaustible Energy Any source of energy that is limited and cannot be replaced when it is used, such as oil, coal, and natural gas.
Fossil Fuel A natural fuel such as coal or gas formed in the geological past from the remains of living organisms.
Geothermal Energy stored in the earth in the form of heat.
Greenhouse Effect The phenomenon where earth's atmosphere traps solar radiation, caused by gases(carbon dioxide, water vapor,& methane) in the atmosphere that allows incoming sunlight to pass through but absorb heat radiated back from the earth
Heat (Thermal) Energy Energy in transit.
Hydroelectric Energy The use of flowing water from waterfalls and dams to produce electricity.
Hydrogen The first and simplest element on the periodic table. It is one of the most common elements in the galaxy.
Inexhaustible Energy An energy source that will never run out.
Joule The unit of energy or work in the MKS system of units, equal to the work done by a force of one Newton-meter.
Kinetic Energy The energy possessed by a body as a result of its motion.
Law of Conservation of Energy Energy can be neither created nor destroyed. There is a fixed amount of energy present in different forms that can be converted from one form to another, but energy does not go away.
Light (Radiant) Energy Energy visible to the eye.
Mechanical Energy Energy produced by mechanical devices, such as gears, pulleys, levers, or internal combustion engines.
Natural Gas Gas usually found within the vicinity of petroleum reserves.
Newton-Meter A unit measure of work.
Non-Renewable Energy A resource that cannot be replaced once used.
Nuclear Energy The power of the atom.
Petroleum Oil.
Photovoltaic Cell A device that converts light into electricity.
Potential Energy The energy that a piece of matter has because of its position or nature or because of the arrangement of parts.
Power The rate at which work is performed or energy is expended.
Power Grid A system by which electrical power is delivered throughout a region.
Renewable Energy A resource that can be replaced when needed.
Solar Energy Energy from the sun.
Sustainable Refers to the use of resources in ways that prevent their being depleted or permanently damaged.
Watt A measure of power equal to one joule of work per second.
Wind Energy Energy derived from wind by means of windmills or wind turbines.
Wind Farm A collection of wind turbines used to create electricity.
Wind Turbine A propeller driven by the wind and connected to a generator. The wind makes it turn the generator, which produces electricity.
Work A result of a force moving an object a certain distance.
