Index fossil
Law of horizontality-original layers of earth laid down in horizontal layers logically older layers are below newer
layers (UNCONFORMITY- a missing layer that is expected. The layer may not have deposited or eroded.
Law of uniformitarianism-the past is key to the presents and via circular argument visa versa
Law of fossil Succession-fossils found in layers under a layer are older than fossils found in the upper layer
Rock formation- a layering of rock with similar characteristics throughout
Rock Column-the different layers of earth
Rock Correlation-when distance separates rock columns or formations, but the characteristics are the same
between the rock columns even though there is distance separating the rock columns or formations
*Index Fossil-a fossil that is easily found, in a vast geographic area, and existed for a short geologically time.
Example trilobites existed only in Paleozoic era, dinosaurs only in Mesozoic era,& humans only in Cenozoic era.
Relative dating-comparison dating
Law of unconformity
Absolute dating-carbon dating or other half life of an element used to date fossils

Boyle’s IDEA GAS Law T MUST BE CONSTANT
PiVi = PfVf
Pi = initial pressure
Vi = initial volume
Pf = final pressure
Vf = final volume
Charles’ IDEAL GAS Law T is in degrees K and V is constant
Vi/Ti = Vf/Tf
Vi = initial volume
Ti = initial absolute temperature
Vf = final volume
Tf = final absolute temperature

Boyle’s IDEA GAS Law T MUST BE CONSTANT
PiVi = PfVf
Pi = initial pressure
Vi = initial volume
Pf = final pressure
Vf = final volume
Question
A balloon filled with an ideal gas at a temperature of 27 °C at 1 atm of pressure. If the
balloon is heated to 127 °C at constant pressure, by what factor does the volume
change?
Vi / Ti = Vf / Tf
Convert temperatures to Kelvin
K = °C + 273
Ti = 27 °C + 273
Ti = 300 K
Tf = 127 °C + 273
Tf = 400 K
Vf = ( Tf / Ti ) x Vi
Vf = ( 400 K / 300 K) x Vi
Vf = 4/3 Vi
Charles’ IDEAL GAS Law T is in degrees K and V is constant
Vi/Ti = Vf/Tf
Vi = initial volume
Ti = initial absolute temperature
Vf = final volume
Tf = final absolute temperature
Sample problems

Question:
A 600 mL sample of nitrogen is heated from 27 °C to 77 °C at constant pressure. What
is the final volume?
Failure to convert to K is the place mistakes are made in this type of problem
T K = 273 + °C
Ti = initial temperature = 27 °C
Ti K = 273 + 27
Ti K = 300 K
T K = 273 + °C
Tf = final temperature = 77 °C
Tf K = 273 + 77
Tf K = 350 K
Vi/Ti = Vf/Tf
Vf = (600 mL)(350 K)/(300 K)
Vf = 700 mL
WATER-gives rise LIFE-The start of preparing for Keystones next year and 4th quarterly this
year. http://www1.lsbu.ac.uk/water/water_hydrogen_bonding.html
H is hydrogen
O is oxygen
Hydrogen bonds with oxygen in a 2:1 ration and forms 1 molecule of water (We drew an
introduction to this molecule in class. Refer to your notes.)
Water has two areas of charge, a positive charge at H and a negative charge at O.
The H is attracted to two atoms at the same time. Therefore, water molecules share electrons
to bond 4 water molecules together with an equal distance from the center oxygen atom.
This equal distance, or predetermined maximum distance for specific properties of water to
exist, makes water unique.
NOTICE ONLY 4 MOLECULES OF WATER ARE ATTACHED AT THE CENTER OXYGEN ATOM.
SQUEEZING A FIFTH WATER MOLECULE IN WOULD SPREAD THE OTHER 4 MOLECULES TOO FAR
APART TO HOLD ONTO THE UNIQUE PROPERTIES OF WATER.
For example, water expands when frozen and becomes less dense so ice floats in liquid
water. PRODUCTS
