Combustion - -A chemical process of changes in size, shape, or appearance.
oxidation that occurs at a rate fast enough to
produce heat and usually light in the form of
either a glow or a flame. Chemical change occurs when... - -a
substance changes from one type of matter into
another, such as two or more substances
Fire - -A rapid oxidation process, which is combining to form compounds.
a chemical reaction resulting in the evolution of
light and heat in varying intensities.
Energy - -the capacity to perform work
Heat - -A form of energy characterized by
vibration of molecules and capable of initiating Work - -occurs when a force is applied to
and supporting chemical changes and changes an object over a distance or when a substance
of state. undergoes a chemical, biological, or physical
change.
Temperature - -Measure of a material's
ability to transfer heat energy to other objects; Oxidation - -chemical process that occurs
the greater the energy, the higher the when a substance combines with an oxidizer
temperature. Measure of the average kinetic such as oxygen in the air; a common example is
energy of the particles in a sample of matter, the formation of rust on metal
expressed in terms of units or degrees
designated on a standard scale.
Potential energy - -stored energy
possessed by an object that can be released in
Fuel - -A material that will maintain the future to perform work once released.
combustion under specified environmental
conditions.
Kinetic energy - -the energy possessed by
a body because of its motion
oxidizer - -Any matieral that readily yields
oxygen or other oxidizing gas, or that readily
reacts to promote or initiate combustion of Potential chemical energy of a fuel is converted
combustible materials. to... - -thermal energy and released as heat
Matter - -anything that occupies space and Types of energy - -chemical, thermal,
has mass mechanical, electrical, light, nuclear, and sound
Physical change occurs when... - -a Joules - -The measure for energy in the
substance remains chemically the same but International System of Units (SI). 4.2 joules
