Anything that takes up space and has mass
Measure of the amount of matter it contains (remains the same no matter what, gravity, etc.)
Smallest particle that contains the chemical properties of an element
Substance composed of atoms, cannot be broken down
List of all elements currently known
Particles containing more than one atom
Molecules that contain more than one element
# of Protons in the nucleus
# of Protons + # of Neutrons
Different # of Neutrons
Release of material from the nucleus. Breaks it down into a simpler element.
Time it takes for 1/2 the original radioactive parent atom to decay.
Sharing electrons (stronger)
Steals electrons (weaker)
Weakest chemical bond between an electronegative hydrogen atom and another electronegative atom
One side more positive and one side more negative
Cohesion of water molecules at the surface of water.
Adhesion of water molecules to a surface is stronger than cohesion between the molecules. (Paper towel. sponge)
Substance contributing hydrogen ions to a solution
Substance contributing hydroxide ions to a solution
Shows strength of acids and bases
When atoms separate from the molecules they are a part of or recombine with other molecules.
Law of Conservation of Matter
Matter can't be created or destroyed
Carbon, Hydrogen, Oxygen. Glucose Monosacharides etc.
Amino acids, chains, etc.
DNA, RNA. Organic compounds in all living cells. Genetic material to be passed down.
Nonpolar Molecules, high energy, etc.
Highly organized living entity that consists of 4 types of macro-molecules and other stuff in a watery solution. Surrounded by a membrane.
Ability to do work or transfer heat
Visible, UV Infrared energies
Massless packets of energy that travel at the speed of light.
Amount of energy used when a 1 watt light bulb is turned on for 1 second. (Very small)
Rate at which work is done
Stored Energy/Energy being used
Energy is not created or destroyed/As energy is used, the ability to do work is diminished.
Ration of the amount of work that is done to the total amount of energy that is introduced into the system to begin with.
Ease which an energy source can be used for work
Randomness in a system always increasing.
Stuff in/Nothing into the system
Stuff goes in/out
Determining inputs, outputs and changes in the system under different conditions
Inputs = Outputs. No change to the system
Rate of the process feeding back into the system
Neg/Pos Feedback loop
System goes back to original state/increasing levels of stuff.
Adaptive Management Plan
Planning for future problems.
