The Boyle’s Law and the
Gay-Lussac’s Law express experimental relationships between two of
the three parameters characterizing the state of gas, the pressure,
volume, and temperature, while the third is kept constant. For both
laws state which parameters are variable and which is kept
constant.
The Boyle’s Law and the Gay-Lussac’s Law are special cases of
a more general relationship called the ideal gas law. State the
ideal gas law. Why do we use the absolute temperature (temperature
in kelvins)...
1 Ideal Gas Law The ideal gas law is familiar to anyone who has
taken a college chemistry course: P V = νRT. This problem will show
you why the ideal gas law has this form. We can arrive at this
expression just by using classical mechanics! Consider a box of
volume V containing N particles, each having mass m, that are
moving horizontally with average speed v. The particles bounce back
and forth between the end walls of the...
According to Boyle’s law, for a certain gas, pressure an volume
are inversely proportional: P = 800/V where V is measured in and
pressure P in pounds per square inch.
a) Find the rate of change of P when V=20 , and interpret its
meaning (carefully state the units).
b) Find the average rate of change of P when V changes from 20 to
25 . Compare your result with a).
What is an ideal gas law? How did scientist arrive at the
present day ideal gas equation. (Hint: explain different gas laws
and how you come to ideal gas law equation using all the laws)
According to the ideal gas law, a 1.041 mol
sample of carbon dioxide gas in a
1.016 L container at 270.0 K
should exert a pressure of 22.70 atm. By what
percent does the pressure calculated using the van der Waals'
equation differ from the ideal pressure? For
CO2 gas, a = 3.592
L2atm/mol2 and b =
4.267×10-2 L/mol.
%
Hint: % difference = 100×(P ideal - Pvan
der Waals) / P ideal
According to the ideal gas law, a 9.776 mol sample of xenon gas
in a 0.8177 L container at 499.7 K should exert a pressure of 490.2
atm. By what percent does the pressure calculated using the van der
Waals' equation differ from the ideal pressure? For Xe gas, a =
4.194 L2atm/mol2 and b = 5.105×10-2 L/mol.
