sound waves
sound wave
Sound is a mechanical wave that results from the back and forth vibration of the particles of the medium through which the sound wave is moving
energy
ability to do work, which is the ability to exert a force causing displacement of an object.
pixel
A pixel is the smallest unit of a digital image or graphic that can be displayed and represented on a digital display device.
temperature
temperature (sometimes called thermodynamic temperature) is a measure of the average kinetic energy of the particles in a system
expand VEI
Volcanic Explosivity Index
amplitude
the maximum extent of a vibration or oscillation, measured from the position of equilibrium.
recoil
to undergo a change in momentum as a result either of a collision with an atom, a nucleus, or a particle or of the emission of a particle.
electron
An electron is a negatively charged subatomic particle. It can be either free (not attached to any atom) or bound to the nucleus of an atom.
thermal equilibrium
the relationship between two systems connected only by a diathermic wall.
OR
the relationship between two isolated systems the states of which are such that no net transfer of energy would occur between them if they were connected by a diathermic wall.
magma
extremely hot liquid and semi-liquid rock located under Earth’s surface
crest
A crest is the point on a wave with the greatest positive value or upward displacement in a cycle.
friction
the resistance to motion of one object moving relative to another.
polarization
polarization is a property applying to transverse waves that specifies the geometrical orientation of the oscillations.
entropy
the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work.
cinder cone
trough
A trough is the opposite of a crest, so the minimum or lowest point in a cycle.
Newtons 2nd Law
the rate of change of momentum of a body over time is directly proportional to the force applied and occurs in the same direction as the applied force.
radiation
radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium
absolute zero
the temperature at which a thermodynamic system has the lowest energy. It corresponds to −273.15 °C on the Celsius temperature scale and to −459.67 °F on the Fahrenheit temperature scale.
name at least 3 types of volcanoes
acoustic
a branch of physics that deals with the study of mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound, and infrasound.
Newtons 1st Law
if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
photon
A photon is the smallest discrete amount or quantum of electromagnetic radiation. It is the basic unit of all light. Photons are always in motion and, in a vacuum
closed system
a closed system is a type of thermodynamic system where mass is conserved within the boundaries of the system, but energy is allowed to freely enter or exit the system
