Question

identify the process that is represented by each model below.
freezing
melting
process a
process b

Explanation:

Step1: Analyze Process A

In Process A, the particles start in a liquid - like (more disordered, but still close) state in the container and then form a highly ordered, closely packed solid - like structure. Freezing is the process where a liquid turns into a solid, which matches the change from the liquid - like arrangement to the solid - like arrangement of particles. So Process A represents freezing.

Step2: Analyze Process B

In Process B, the particles start in a solid - like (ordered, closely packed) structure and then move into a liquid - like (more disordered, but still close) state in the container. Melting is the process where a solid turns into a liquid, which matches the change from the solid - like arrangement to the liquid - like arrangement of particles. So Process B represents melting.

Answer:

Process A: freezing
Process B: melting
