Descriptions
Gives the relationship between volume and and temperature if pressure and amount of gas are held constant.
Charles' Law
PV=nRT
What does the P stand for?
what is pressure?
P x V=kB
Boyle's Formula
A high altitude balloon is filled with 1.41 x 104 L of hydrogen at a temperature of 21 degrees C and a pressure pf 745 torr. What is the volume of the balloon at a height of 20 km, where the temperature is -48 degrees C and the pressure is 63.1 torr?
1.2741 x 104 L
What is the gas law constant?
The gas constant (also known as the molar, universal, or ideal gas constant) is denoted by the symbol R or R. It is equivalent to the Boltzmann constant, but expressed in units of energy per temperature increment per mole.
states that volume of a given amount of gas held at constant temperature varies inversely with the applied pressure when the temperature and mass are constant.
Boyle's Law
PV=nRT
What does the n stand for?
what is number of moles?
P/T=kB
Gay Lussac's Formula
A sample of oxygen gas collected in the lab occupies a volume of 250 mL when its pressure is 720 mmHg. What volume will the gas occupy at a pressure of 760 mmHg if the temperature is held constant?
237 mL
Why is the motion of one particle in a gas independent of the motion of the other particles?
no attractive or repulsive forces exist between the particles.
states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature.
Gay Lussac's Law
If you cool the molecules down, they will be slow, and the pressure will _____________.
Decrease
V/T = kB
Charles' Formula
A sample of Ne gas occupies 0.220L at 0.86 atm. What will be its volume at 29.4kPa?
.66 L
If the volume of a fixed amount of gas is tripled at a constant temperature, what happens to the pressure?
Volume and pressure are inversely proportional. The pressure decreases by a factor of 3.
at the same temperature and pressure, equal volumes of gases contain equal numbers of moles.
Avagadro's Law
Relationship between pressure, volume, and temperature.
PV/T=k
V/N =kB
Avagadro's Formula
If the pressure in a car tire is 1.88 atm at 25°C, what will be the pressure if the temperature warms to 37°C?
1.9 atm
What must be equal in Boyle's law?
amount of gas, and temperature
A combination of the laws presented above generates the Ideal Gas Law.
The ideal gas law
The total pressure exerted is ________ to the sum of the partial pressures of the individual gases
Equal
PV=nRT
The Ideal Gas Formula

808 L
101, 325 pascals equals ___ ATM
1 ATM
