Which 1859 result is called the first-ever statistical law in physics?

  1. Dalton's partial pressure law
  2. Maxwell's velocity distribution
  3. Avogadro's equal volume law
  4. Graham's law of gas diffusion
Show answer and solution

Correct answer: B. Maxwell's velocity distribution

Maxwell's 1859 velocity distribution gave the share of molecules in each speed range, a statistical law.

August Krönig's gas model of 1856 considered which kind of molecular motion only?

  1. Rotational motion
  2. Vibrational motion
  3. Translational motion
  4. Electronic motion
Show answer and solution

Correct answer: C. Translational motion

Krönig's simple model kept only translation, while Clausius later added rotation and vibration.

Collisions being strictly binary and uncorrelated means

  1. particles hit only container walls
  2. three-body collisions dominate
  3. only two-body hits, with no memory
  4. particles stay paired for ever
Show answer and solution

Correct answer: C. only two-body hits, with no memory

Each collision involves just two particles, and particles keep no memory of earlier collisions.
