Question

the diagram below shows the different phase transitions that occur in matter. which arrow would most likely represent the phase change that involves the same amount of energy as arrow 1? 2 3 4 5

Explanation:

Step1: Understand phase - change energy

Phase - change energy is the energy required to change the state of matter. The energy required to go from solid to liquid (melting) is the same as the energy required to go from liquid to solid (freezing). The energy required to go from liquid to gas (vaporization) is the same as the energy required to go from gas to liquid (condensation).

Step2: Identify arrow 1

Assume arrow 1 represents a phase - change process. If arrow 1 represents melting (solid to liquid), then the phase - change process with the same amount of energy is freezing (liquid to solid).

Step3: Match with options

If arrow 1 is melting, the reverse process (freezing) is represented by an arrow going from liquid to solid. Among the options, if we assume a standard phase - change diagram layout, the arrow representing the reverse of the phase - change of arrow 1 is the one that represents the opposite transition. If arrow 1 is from solid to liquid, the arrow with the same energy is from liquid to solid. Let's assume arrow 1 is solid - to - liquid, then arrow 2 (liquid - to - solid) has the same amount of energy involved.
