Modules 1-5
Two or more atoms linked together to make a substance with unique properties.
What is an molecule?
The number of protons in an atom.
What is the atomic number?
The temperature scale in which water boils at 100 degrees and freezes at 0 degrees.
What is Celsius temperature scale
The mass of air surrounding a planet.
What is Atmosphere?
Newton's First Law of Motion
An object in motion will tend to stay in motion until it is acted on by an outside force.
The moisture content of air.
What is Humidity
The brightness of a star seen in the star. The smaller the number, the brighter the star.
What is Apparent Magnitude?
The process by which a portion of a glacier breaks off and begins floating in the sea as an iceberg
What is calving?
The region of the earth's atmosphere between altitudes of roughly 80 kilometers and 460 kilometers.
What is the thermosphere?
Newton's theory of light.
What is the Particle Theory?
Energy that is transferred as a consequence of temperature differences.
What is heat?
Acceleration
What is: "The time rate change of an objects velocity?"
The process by which oxygen reacts with a fuel to release energy.
What is combustion?
The region of the atmosphere that extends from ground level to roughly 11 kilometer above sea level.
What is the troposphere?
For every action there is an equal and opposite reaction.
What is Newton's Third Law of Motion?
The use of electricity to break a molecule down into smaller units.
What is electrolysis?
The the process by which a radioactive isotope changes by emitting a 4He nucleus.
Alpha Decay
What is critical mass?
The amount of isotope necessary to sustain a chain reaction.
What is the homosphere
The lower layer of the earth's atmosphere , which exists from ground level to roughly 80 kilometers above sea level.
Newton's Second Law of Motion
when an object is acted on by one or more outside forces, the total force is equal to the mass of the object times the resulting acceleration.
(Or Total Force = (Mass) x (Acceleration)
The composition of dry air.
What is 78% nitrogen, 21% oxygen, and 1% other gases.
Additive Primary Colors
The colors red, green, and blue, which can be added in different proportions.
What is a comet?
A relatively small, frozen body that travels around the sun, typically in a highly elliptical orbit.
The upper layer of the earth's atmosphere, which exists higher than roughly 80 kilometers above sea level.
what is the heterosphere?
What was the book that Newton published in 1704 that discussed light.
What is Optiks (pg. 367)
