Key Terms 2

Boyle’s Law
volume and pressure are inversley related
Charles’ Law
volume and temperature are directly related
Gay Lussac’s Law
pressure and temperature are directly proportional
Avogrado’s Law
the volume of gas is directly proportional to the amount of a gas at a constant temperature and pressure
Vapor Pressure
pressure exerted by a vapor of gas that is in equilirium with its solid of liquid phase
Dalton’s Law of Partial Pressure
total pressure is the sum of the pressure of all gases
Solution
homogeneous misture, exsists in one phase
Solubility
maximum amount of solute that can dissolve in 100g of solute at a given temperature
Concentration
amount of solute dissolved
Dilute
relatively small amount of solute dissolved
Concentrated Solution
relatively large amount of solute dissolved
Acid
H+, sour, pH below 7
Base
OH-, bitter, pH above 7
Titration
determines concentration of unknown solution using standard solution
Buffer
solution made from a weak acid or base and its salts, resists changes in pH
Heat
total kinetic energy
Temperature
average kinetic energy
Law of Conservation of Energy
energy cannot be created or destroyed but only change form
Entropy
measure of disorder in a system
Spontaneity
reaction will proceed without any outside interaction
Calorimeter
insulated device used to measure the heat transfer in a chemical process; the temperature change of a precise amount of water surrounding the system is measured
Collision Theory
new products are formed when particles collide with one another
Reaction Rate
amount of energy for a reaction
Le Chatelier’s Principle
a system at equilibrium will shift to reestablish equilibrium when stressed
