List the six physical properties of gases
Diffusion Effusion Permeability Fluidity Compressibility Expansibility
The ability of a gas to mingle with or pass through another porous substance
Permeability
When gases experience low pressure, they quickly expand to fill the available space, this is called
Expansibility
What are the values of standard temperature and pressure (STP)
0°C 273 K 760 torr 101,325 Pa 1 atm
Robert Boyle found that pressure was__ proportional to volume
Inversely
What says that the volume of a dry gas is inversely related to the pressure if the temperature is held constant
Boyles law
Temperature and volume are__proportional when pressure is constant
Directly
What says that when the pressure on a sample of dry gas is held constant, the temperature in kelvin’s and volume are directly related
Charles law
What says the pressure is directly proportional to temperature in kelvin’s for a fixed mass of gas held in a constant volume
Gay-Lussac’s law
What says that the total pressure of a mixture of gases equals the sum of the partial pressures
Dalton’s law of partial pressures
Vapor pressure
Pressure exerted by vapor
One mole of gas at STP
22.4 L
Gas density is measured in
Grams per liter
The ideal gas law is expressed how?
PV = nRT
What does n stand for
The number of moles of gas in a sample problem
