a student is examining three diagrams that show particle arrangements in a solid, liquid, and gas. which sequence of particle diagrams represents decreasing kinetic energy of the particles? q→r→s s→q→r r→s→q r→q→s
Answer
# Explanation:
## Step1: Recall particle - energy relationship
Particles in a gas have the highest kinetic energy, followed by liquid and then solid.
## Step2: Identify states in diagrams
Diagram R shows particles spread out, representing a gas. Diagram Q shows particles somewhat close but able to move past each other, representing a liquid. Diagram S shows particles closely packed in a fixed pattern, representing a solid.
## Step3: Determine order of kinetic energy
The order of decreasing kinetic energy is gas (R) → liquid (Q) → solid (S).
# Answer:
R→Q→S
