Physics - Unit 3.3: Kinetic Theory

Boyle’s Law

Pressure(p)∝1/volume(v) at constant (T)

Grey-Lussac’s Law

Pressure(p)∝temperature at constant V

Charles’ Law

Volume(V)∝temperature at constant p

What is the equation for the relationship between the 3 laws

pV=nRT

where n is the number of moles of gas and R is the molar gas constant=8.31 Jmol^-1K^-1

What is another equation for the relationship between the 3 laws

pV=NkT

where N is the number of particles and k is the Boltzmann constant=1.38×10^-25JK^-1

What are the assumptions about gases

RAVED

R—>Random motion

A—>Attraction (none between particles)

V—>Moles/Particles have negligible volume

E—>Elastic collisions. E_k is conserved

D—>Duration of collisions. Very short
