Question

which best compares the particles of the substance when it is in region 1 with the particles of the substance when it is in region 3? the particles are slower in region 3. the particles are more orderly in region 1. the particles have more kinetic energy in region 1. the particles have less freedom of motion in region 3.

Explanation:

• Region 1: Likely a solid state (lower temperature). Particles in a solid are closely packed and have a more orderly arrangement.
• Region 3: Likely a liquid state (higher temperature than region 1). Particles in a liquid have more freedom of movement compared to a solid but are less orderly than a solid. Kinetic energy is related to temperature (higher temperature in region 3 means more kinetic energy in region 3 particles). Particle speed is related to kinetic energy (faster in region 3).

Answer:

B. The particles are more orderly in region 1.
