Gas Laws Flashcards
An imaginary gas that perfectly fits all the assumptions of the kinetic-molecular theory.
Ideal gas
A pressure 1mmHg is now called 1 ____ in honor of Torricelli for his invention of the barometer.
Torr
A gas that does not behave completely according to the assumptions of the kinetic-molecular theory.
Real gas
This law states that the total pressure of a mixture is equal to the sum of the particle pressure of the component gases.
Dalton’s Law of Partial Pressures
This is the agreed-upon standard conditions of exactly 1atm and 0* C.
Standard Temperatures and Pressures (STP)
The volume of a fixed mass of gas varies inversely with pressure at constant pressure.
Boyle’s Law
kPa, Torr, ATM, mmHg
Units of Pressure
PV=nRT
Ideal Gas Law
P1V1=P2V2
Boyle’s Law
The temperature -273.15*C, given a value of zero in the Kelvin scale.
Absolute zero
A process by which gas particles pass through a tiny opening.
Effusion
Spontaneous mixing of the particles of 2 substances caused by their random motion.
Diffusion
The pressure of each gas in a mixture.
Partial Pressure
A collision between gas particles & container walls in which there is no net loss of kinetic energy.
Elastic collision
A device used to measure atmospheric pressure.
Barometer
