Mathematical Rep Flashcards
What does Boyle’s law relate?
Pressure and volume.
What does Charles’s law relate?
Temperature and volume.
What does Avogadro’s law relate?
The number of moles and volume.
What does Graham’s law relate?
The rate of effusion and the molar mass of a gas.
What do the combined and ideal gas laws explain?
Gas behavior for gases not near their condensation points.
What does the combined gas law describe?
Systems in which pressure, volume, and temperature change.
PiVi/T = PaV2/T2
What is the ideal gas law?
It combines all relationships described by Boyle’s law, Charles’s law, and Avogadro’s law with the universal gas constant, R.
PV = nRT
What is the standard temperature and pressure (STP) for gases?
273.15 K and 1.00 atm.
What is the molar volume of an ideal gas at STP?
22.4 L/mol.
How is the density of a gas related to its molar mass and molar volume?
Density (d) is related to molar mass and molar volume.
PM = dRT
What does the ratio of partial pressure to total pressure indicate?
It is proportional to the ratio of moles of that gas to the total number of moles.
What happens when gases are sufficiently cooled and compressed?
We can no longer ignore the volume of gas particles or the attraction between them, requiring a modification of the ideal gas law determined by van der Waals.
