Ideal Gases Flashcards
Boyle’s Law
The pressure exerted by a fixed mass of gas is inversely proportional to it’s volume, provided the temp of the gas remains constant.
What is Brownian motion?
The erratic motion of particles.
Factors that affect pressure.
- The number of particles that hit each side of the box in one second.
- The force with which the particle collides with the wall.
Charle’s Law
For a fixed mass of gas it’s temperature is directly proportional to its volume.
What is an ideal gas?
This is a gas for which we can apply the equation “pv/T=constant “ for a fixed mass of gas
OR
A gas which obeys the ideal gas equation (PV=nRT)
Pressure of molecules.
p = Nm / l³ (multiply by ¹/₃ when considering all dimensions)
Force exerted by one molecule.
F = mc² / l. (when considering all molecules multiply by N ,which is the total number of particles in the gas)
Formula of Avogadro constant. (Na)
N/ n (n is moles and N is number of particles)
Boltzmann constant. (k)
R /Na ( R is 8.31 and Na is the Avogadro constant)
Relationship between the translational kinetic energy and the thermodynamic temperature.
½m = ³/₂kT
What is translational kinetic energy?
This is the energy a molecule has because it is moving along.
