Energy and Matter

Which of these best describes the motion of particles?

• Particles diffuse from area of lower concentration to higher concentration in a random motion

• Particles stay in one place and do not move freely

• Particles diffuse from area of higher concentration to lower concentration in a random motion

• Particles diffuse from areas of lower concentration to higher concentration in LIQUIDS and SOLIDS ONLY
