Question

a chemistry professor is preparing a lesson on the phases of matter. read the piece of information in each row, then select the section where it fits best. matter undergoes a phase change when enough energy is added or removed to alter its physical state (liquid, solid, or gas). water changes from a liquid phase to a solid phase (ice) when its temperature decreases to 0°c or lower.

Explanation:

• The first statement is a general description of what phase change is, so it belongs to "Definitions".
• The second statement gives a specific instance (water changing from liquid to solid), so it belongs to "Examples".

Answer:

• First row: Definitions
• Second row: Examples
