Question

Quizplus · Accepted Answer

Starting at point C, the substance is in the liquid state. As the pressure is increased and the substance moves towards point B, the temperature remains constant, indicating a phase transition is occurring. At point B, the substance is in the gas phase, indicating that it has undergone a phase change from liquid to gas, which is called vaporization. Therefore, the correct choice is B.
