3.2 Modelling gasses

Question 1

Brownian motion

Answer 1

Brownian motion or pedesis is the random motion of particles suspended in a fluid (a liquid or a gas) resulting from their collision with the fast-moving molecules in the fluid.

Question 2

1/2mc̄^2 = 3/2k_bT

Answer 2

Kinetic energy.
c̄: average speed of gas particles
k_b: Boltzmann’s constant (1.3*10^(-23)J/K)

Question 3

p = F/A

Answer 3

pressure = force/area
