Gases naturally move from areas of ____ pressure to ___ pressure.
Pressure and the number of molecules are _________ related.
As volume decreases, pressure __________.
Raising the temperature of a gas increases the _______, if the volume is held constant.
Gas pressure is inversely proportional to the volume when temperature is held constant. (Whose law?)
P1V1 = R2V2
Boyle's Law's equation?
The volume of a fixed mass is directly proportional to the Kelvin temperature when pressure is held constant.(Whose law?)
Gas law problems involving temperature will always require that the temperature be in ________.
Gay Lussac's Law
The pressure and Kelvin temperature of a gas are directly proprtional, provided that the volume remains constant. (Whose law?)
The Combined Gas Law
_____________ expresses the relationship between pressure, volume and temperature of a fixed amount of gas.
If the temperature remains constant use...
If the pressure remains constant use...
If the volume remains constant use...
the volume occupied by a mole of any gas at STP
the mass of a mole of any element or compound
the number of grams of an element is numerically equal to the atomic mass of the element in amu
the number of representative particles of a substance in 1 mole of that substance
an atom, an ion, or a molecule, depending upon the way a substance commonly exists
the SI unit used to measure each amount of substance
standard temperature and pressure
0 degrees celsius and 1 atm
the percent by mass of each element in a compound
the smallest whole number ratio of the atoms in a compound
number of molecules
this quantity can always be used in the same way as moles interpreting balanced chmical equations
this is conserved in reactions where the temperature is constant and the number of moles of gaseous reactants is the same as that of gaseous products
this is conserved in every ordinary chemical reaction
the reactant that determines the amount of product that can be formed in a reaction
the maximum amount of product that could be formed from given amounts of reactants
the reactant that is not completely used up in a reaction
the amount of product formed when a reaction is carried out in the laboratory
the ratio of the actual yield to the theoretical yield
vaporization at the surface of a liquidthat is not boiling
the conversion of a liquid to a gas below the boiling point
the temperature at which the vapor pressure of a liquid is equal to the external pressure
normal boiling point
the temperature at which the vapor pressure of a liquid is equal to 1 atmosphere
the temperatre at which a solid changes into a liquid
the change of a solid directly to a vapor
all matter consists of tiny particles that are in constant motion
the energy an object has due to its motion
a device used to measure atmospheric pressure
the pressure resulting from the collision of atoms and molecules with objects
a measure of the force exerted by a gas above a liquid
