Gas Laws Flashcards
Boyles law
pV= constant
Charles law
V/T= constant
What is isobaric change
Any change at constant pressure
Charles law explanation
Work is done to change volume of gas
Energy transferred to gas and it heats up
Pressure law
p/T= constant
What is Brownian motion
Random motion of particles suspended in a medium
What shows the existence of molecules and atoms in a gas
Brownian motion
What is avogadros constant
Defined as the number of atoms in 12 grams of carbon 12/6
What is a molar mass
The mass of one mole of a substance
Number of molecules in terms of moles
Na x Ms/M
What is the ideal gas equation
pV=nRT
What is an ideal gas
One that obeys Boyles law
What is the value of pV/T equal to
R
The molar gas constant
What is shown on the graph of pV against T for n moles
Gradient is nR
Gives the equation pV=nRT
What are N and k in pV=NkT
N is the number of moles
k is the Boltzmann constant
What is the Boltzmann constant equal to
k=R/Na
What is Crms equal to
Root((sum(c^2))/N)
What is the kinetic theory equation
pV=(Nm(Crms)^2)/3
