Glossary - Energy Transformation
A
atom: one of the tiny particles that matter is made of
L
law of conservation of energy: the basic principle that energy can never be created nor destroyed, just transferred between objects and transformed between different types
S
Sankey diagram: a diagram that shows how energy is transferred and/or transformed by a process or device; each type of energy involved is represented as an arrow; the thickness of each arrow indicates the amount of energy of that type; the combined thickness of the "input" arrows must equal the combined thickness of the "output" arrows because of the law of conservation of energy
C
chemical bond: an attraction between two atoms that holds them together
chemical potential energy: energy that is stored in the chemical bonds of substances
, such as foods, fuels and batteries
chemical reaction: the rearrangement of atoms to form one or more new substances
P
pacemaker: a device that helps keep the heart beating regularly
potential energy: energy that is stored in an object
E
efficiency: a measure of how much of the total energy supplied to a device is used, rather than wasted; efficiency = (useful energy) / (total energy input)
energy: the capacity to do work; energy comes in different forms
(light, heat, electricity) and can be transferred from one object to another or transformed from one type to another, but never created nor destroyed
energy consumption: the amount of energy a device or process uses in a certain period of time, measured in watts
energy transfer: the movement of energy from one object to another, possibly undergoing a transformation at the same time
energy transformation: the conversion of energy from one type to another
M
molecule: a group of atoms held together by bonds, e.g. a water (H2O) molecule
J
joule (J): the standard unit of energy or work
K
kinetic energy: the energy an object has because of its motion
T
temperature: the temperature of an object depends on the average kinetic energy of the molecules it contains; the hotter the object is, the more kinetic energy its molecules have
W
waste energy: the energy supplied to a device that is not put to use, usually escaping to the surroundings as heat and sound
watt (W): a unit of power, used to measure how much electricity a power plant produces or how much electricity a device uses
