Ideal Gases Flashcards
State Charles’ law.
At constant pressure, volume is directly proportional to absolute temperature. V/T=constant
State Boyle’s law.
At constant temperature, pressure and volume are inversely proportional. pv=constant. An ideal gas obeys this law at all temperatures.
State the pressure law.
At constant volume pressure is directly proportional to absolute temperature. p/T=constant.
State the equation that combines all three gas laws.
(pv)/T=constant
State the assumptions of the kinetic theory of gases. (There are seven).
1) The gas contains a large number of particles.
2) The particles move rapidly and randomly.
3) The motion of the particles follows Newton’s laws.
4) Collisions between particles or the particles and the walls of the container are perfectly elastic.
5) There are no attractive forces between particles.
6) The time taken for a collision to happen is negligible compared to the time between collisions.
7) Particles have negligible volume compared with the volume of the container.
What is the Avogadro constant?
The number of particles in one mole of a substance.
Give the two ideal gas equations and state when you would use each.
pV=nRT is used when working with amounts of moles.
pV=NkT is used when working with single particles.
When do we use E=3/2kT?
To find the average kinetic energy of a single particle.
