Question

A typical phase change diagram is shown below. What are the correct names of the numbered
arrows?
A phase change diagram showing rising temperature on the y-axis and increasing heat energy on the x-axis. The graph of the line, moving left to right, indicates that heat energy and temperature increase steadily. Temperature levels off while heat energy continues to increase. Phase change 1 indicates energy is decreasing. Phase change 2 indicates energy is increasing. Between number 2 and 3, moving left to right, both energy and temperature continue to increase until phase changes 3 and 4. Pha
