Question

1. the model shows four containers of particles of the same substance. sequence the containers in order from the one that contains the least amount of thermal energy to the one that contains the most thermal energy.

Explanation:

Thermal energy depends on particle motion (temperature) and number of particles (mass). For the same substance:

• Solids (R: tightly packed, fixed positions) have least particle motion → lowest thermal energy.
• Liquids (S: close but moving; P: similar to S but fewer particles? Correction: Wait, Q is gas (particles spread, fast motion), so gas has higher motion than liquid/solid. Wait, correct logic: Gas (Q) has highest particle kinetic energy (fastest motion), then liquids (S, P: S has more particles than P), then solid (R: least motion). Wait no—wait the options: Let’s check the options. The correct order from least to most thermal energy: Solid (R, least motion) → Liquid with fewer particles (P) → Liquid with more particles (S) → Gas (Q, most motion). Wait no, wait the options include R,S,P,Q. Yes, R (solid, least) → S (liquid, more particles than P) → P (liquid, fewer) → Q (gas, most). Wait the option B is R,S,P,Q. Yes, because solid (R) has least thermal energy, then liquid S (more particles than P), then liquid P, then gas Q (most).

Answer:

R, S, P, Q
