Question

order the following from hottest to coldest.
images of containers a, b, c, d with particle motion arrows
multiple - choice options: cbad, dcab, dabc, dbac

Explanation:

Step1: Recall Kinetic Theory

In the kinetic theory of matter, the hotter a substance is, the more kinetic energy its particles have, meaning they move faster and have greater separation (longer arrows, more vigorous motion). Colder substances have particles with less kinetic energy (shorter arrows, slower motion).

Step2: Analyze Particle Motion

• Container C: Particles have the longest arrows, indicating the most vigorous motion (hottest).
• Container B: Particles have medium - long arrows, less vigorous than C but more than A and D.
• Container A: Particles have shorter arrows than B, more motion than D.
• Container D: Particles have the shortest arrows, least vigorous motion (coldest).

So the order from hottest to coldest is C (hottest), B, A, D (coldest), which is CBAD.

Answer:

A. CBAD
