Chemistry
What is a Ion?
A Ion is to react, some elements gain/lose electrons causing them to have a change.
Define renewable energy
Renewable energy doesn't take millions of years to renew
What is a Red Giant?
The outer layer expands and it has a dense core
LIST energies on the spectrum by wavelength: longest to shortest
Radio, Microwave, Infrared, Visible, Ultra Violet, X-ray, GAMMA
What are some positives/negatives of Nonrenewable energy?
(Positives, Inexpensive, Already established) (Negatives, Take a long time to renew0
What is a Isotope?
A Isotope is elements that have the same mass but different electrons.
What are some examples of Renewable energy
-Wind -Solar
Three steps our sun would take on a star life cycle?
Planetary Nebula, White Dwarf and Black Dwarf
LIST colors on within the visible spectrum by wavelength: longest to shortest
Red-->Green-->Violet
What is a gravitational potential?
It uses potential energy and that is energy that is stored. ( As in holding a ball)
What are Valence Electrons?
Its the number of electrons on the outer shell (determines periods)
What are some positives and negatives of renewable energy
(Positives, Renewable, Good for the environment) (Negatives, Expensive, Not common)
Four steps a larger star would take
Super giant, Super nova, Nutron star, Black hole
What characteristic determines a star's life path?
Mass
What is the first law of thermodynamics?
Energy that can not be created or destroyed, it can only be transferred
What is Exothermic?
Energy that is released
Define Nonrenewable Energy
Not renewable and it takes a long time to rebuild
Define fission and give an example of where it occurs
Fission is breaking apart, it occurs on earth
Hubble's law evidence and how it supports the big bang theory
The Universe is constantly expanding
What is the second law of thermodynamics?
Each time energy is transferred it becomes less and less. This "less useful" energy is often released as heat
What is Endothermic?
The energy that is used and takes/stores
What are some examples of Nonrenewable energy
-Coal -Uranium -Oil
Define Fusion and give an example of where it occurs
Fusion is fusing together, it occurs in stars
The Cosmic Microwave Background Radiation and how it supports the big bang theory
It always as a red shift
What are the forms of thermodynamics?
Chemical, Potential, Kinetic, etc..
