1. Temperature – measure of hotness or coldness​
2. Pressure – physical force exerted on an object​
3. Intermolecular Attraction – force that determines the physical properties of a substance​
4. Thermal Energy – energy contained in a system that determines temperature...HEAT​
5. Triple Point Diagram – diagram that shows the three states of matter for a substance​
6. Kinetic Energy – the energy of particles in motion​
7. Open System – can exchange matter and energy with its surroundings..."open"​
8. Closed System – cannot exchange matter and energy with its surroundings..."sealed"​
9. Solid – Definite shape, Definite volume, least energy ​
10. Liquid – NO definite shape, Definite volume, mid energy​
11. Gas – NO Definite shape or volume, most energy ​

1. Release – to give off or go out​
2. Absorb – to take in​
3. Solute – dissolved into solvent...salt (less)​
4. Solvent – dissolves other substances...water (more)​
5. Chemical reaction – changing substances to totally new substances...A + B = C​
6. Thermal Energy – hot or cold​
7. Endothermic – heat absorbed = cooling​
8. Exothermic – heat released = warming​
9. Reactants – factors/molecules on the left side​
10. Products – factors/molecules on the right side

1. Atom – made of protons, neutrons, and electrons​
2. Matter – anything that has mass and takes up space​
3. Element – pure substance made up of only one type of atom​
4. Molecule – group of atoms chemically bonded together​
5. Monatomic – made of only one atom and no bonding ​
6. Diatomic – made up of two atoms bonded​
7. Elemental Molecule – two or more of the same atoms chemically bonded together​
8. Compound Molecule – two or more different types of atoms chemically bonded together​
9. Ionic Bond – bond where electrons are transferred​
10. Covalent Bond – bond where electrons are shared

7. Valence Electron – electrons in the outermost shell​
8. Periodic Table – visual arrangement of chemical elements​
9. Atomic Number – number of electrons in the element​
10. Subatomic Particle – smaller than the atom​
11. Matter – any substance with mass that takes up space​
12. Property – characteristic that can be observed or measured

1. Adaptation- changing to survive in your environment ​
2. Environmental Factor- any factor, whether abiotic or biotic, that influences living organisms​
3. Inherited Factor- alleles/genes passed down from parent to offspring​

5. Population Density – number of organisms in a given area​
6. Carry Capacity – number of organisms an area can healthily support​
7. Stimulus- something that causes a response​
8. Nutrients- essential substances organisms need​
9. Natural Selection- only the fittest and strongest survive​
10. Resistant- unable to be affected by​
11. Modification- a change made to a system
