1. **Stating the problem:** We have three substances A, B, and C in different states with particles shown in boxes. The temperature of substance C is the greatest, and substances A and B have the same temperature. 2. **Understanding particle arrangement and temperature:** - Substance A has densely packed particles, indicating a solid or low temperature state. - Substance B has particles more spread out than A but less than C, indicating a liquid or intermediate temperature. - Substance C has particles most spread out, indicating a gas or highest temperature. 3. **Key concept:** Temperature relates to the average kinetic energy of particles. Higher temperature means particles move faster and are more spread out. 4. **Conclusion:** Since A and B have the same temperature but different particle spacing, this suggests different states or pressures but equal thermal energy. 5. **Summary:** - Temperature C > Temperature A = Temperature B - Particle spacing: C > B > A This matches the description given.
