Kinetic Theory Flashcards
Define Ideal Gas
A gas that strictly obeys the equation of state pV = nRT.
Define the Mole
The amount of a substance containing as many particles as there are atoms in 12g of carbon-12
Define Avogadro’s constant
The number of particles per mole
State four of the assumptions of kinetic Theory for ideal gasses
The motion of molecules is random
The energy between molecules is distributed randomly
All collisions are elastic
Volume of particles is negligible
Define Molar Mass
Mass of one mole of a substance
Define Molecular mass
Mass of a molecule relative to that of the carbon-12 atom.
Define Internal energy
The sum of the kinetic energy and potential energy of all the molecules
Define the Internal energy of an ideal gas
The sum of the kinetic energy of all the molecules
Pressure
The force acting per unit area
Describe how pressure is caused by gas particles in a sealed container
The particles move at high speeds and collide with the walls of the container, this imparts momentum to the container, exerting a force and hence pressure on it.
What is the equation for the mass of one molecule
Molar Mass/ Avogadro’s constant
