Gas Laws Test Flashcards
Pascal
The SI unit of pressure. Equal to the force of one Newton per square inch
Pressure
Measure of the force applied over a unit of area often expressed in units of pascals or pounds per square inch.
Newton
SI unit of measured force. One Newton is equal to the force needed to accelerate a mass of one kilogram one meter per second per second.
Standard temperature and pressure
Reference table A.
101.3 kPa or 1atm.
273k or 0C
Kinetic-molecular theory
A theory used to explain the behavior of gases in terms of motion of their particles
Boyle’s Law
Pressure and volume vary inversely
Charles’ Law
Volume is directly proportional to temperature in an ideal gas
Gay-Luccac’s Law
Density varies inversely with temperature
Avogadro’s Law
Equal volumes of all gases at the same temperature and pressure have the same number of molecules
Ideal gas
Pressure, volume, and temp are related to ideal gas law. Have molecules with insignificant mass and low pressure and high temp
Ideal gas law
Product of pressure and volume of one gram molecule of an ideal gas is equal to the product of absolute temperature of the gas and the universal gas constant
Diffusion
Chemical process where molecules move from a high concentration to a low concentration
Effusion
Movement of gas particles through a small hole. Eye of gas in inversely proportional to square root of mass particles
Graham’s law of diffusion
Under constant temperature and pressure two gases diffuse into eachother at rates inversely proportional to the square roots of their respective molecular weights or densities
Gay-Luccac’s law of combining volumes
