Vibrations And Waves
Something is vibrating.
What is the source of all waves?
Heat flows from an area of higher temperature to an area of lower temperature.
What is the second law of Thermodynamics?
Solid, liquid, gas, and plasma.
What are the phases of matter?
Transfer of heat energy by direct molecular collisions within a substance.
What is conduction?
A measure of the average translational kinetic energy per molecule in a substance.
What is temperature?
What is amplitude?
No substance can reach absolute zero temperature.
What is the third law of Thermodynamics?
The change of liquid to a gas.
What is evaporation?
Transfer of heat energy in a gas or liquid by means of currents in the heated fluid.
What is convection?
Most common unit of heat in the United States. It is the amount of heat required to change the temperature of 1 gram of water by 1o C.
The direction of vibrations relative to the direction of wave travel in a transverse wave.
What is perpendicular?
Energy cannot be created or destroyed, it only transfers from one form to another.
What is the first law of thermodynamics?
The changing of gas to a liquid.
What is condensation?
Transfer of energy by means of electromagnetic waves.
What is radiation?
Three measurements for temperature are ___, ___, and ___.
What is Kelvin, Celsius, and Fahrenheit?
The shift in frequency due to the motion of a vibrating source toward or away from an observer.
What is the Doppler effect?
Two systems, each in thermal equilibrium with a third system, are in equilibrium with each other.
What is the zeroth law of Thermodynamics?
Occurs at 100oC in water.
Warming of the lower atmosphere by short-wave radiation from the Sun that penetrates the atmosphere, is absorbed by Earth, and re-radiated at longer wavelengths that cannot easily escape Earth's atmosphere.
The temperature at which molecules of a substance have their minimum kinetic energy.
What is absolute zero temperature?
The wavelength of longitudinal waves is measured from compression to compression, or ____ to ____.
What is rarefaction?
The first person to coin the term thermodynamics?
Who is Lord Kelvin?
A change of phase from a solid directly into a gaseous phase.
What is sublimation?
The rate of loss of heat from a warm object is proportional to the temperature difference between the object and its surroundings.
What is Newton's law of cooling?
The quantity of heat per unit mass required to raise the temperature of a substance by 1 Celsius degree.
What is specific heat capacity?
