ideal gases Flashcards
total number of atoms equation
N = n x Na
where n is number of moles
Na is Avogadro’s constant
what is avogadros constant
6.02 x10-23 symbol Na
1 mole of any substance has 6.02 x 10-23 atoms in it
assumptions made in the kinetic model for ideal gases
- move in random directions at random speeds
- atoms occupy a negligible volume compared to the volume of the gas
- collisions of atoms with each other and container walls are perfectly elastic
-electrostatic forces between atoms are negligible except during collisions
boyles law
pV = constant
pressure is inversely proportional to volume
if temperature and mass of gas remain constant
pressure and temperature relationship
pressure of ideal gas is directly proportional to temperature
if volume and mass remain constant
combining gas laws
pV/ T = constant
total change in momentum in atom colliding with wall
-2mu
kinetic energy of ideal gases
Kinetic energy of ideal gases is proportional to temperature (IF MEASURED IN KELVIN!!!!)
