ideal gases Flashcards
1
Q
total number of atoms equation
A
N = n x Na
where n is number of moles
Na is Avogadro’s constant
2
Q
what is avogadros constant
A
6.02 x10-23 symbol Na
1 mole of any substance has 6.02 x 10-23 atoms in it
3
Q
assumptions made in the kinetic model for ideal gases
A
- 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
4
Q
boyles law
A
pV = constant
pressure is inversely proportional to volume
if temperature and mass of gas remain constant
5
Q
pressure and temperature relationship
A
pressure of ideal gas is directly proportional to temperature
if volume and mass remain constant
6
Q
combining gas laws
A
pV/ T = constant
7
Q
total change in momentum in atom colliding with wall
A
-2mu
