C:
D:
Correct Answer
B
Explanation
When a certain quantity of pure ice is completely changed to water at 0°C, a phase transition occurs. At this temperature, ice undergoes a process called melting, where it absorbs heat energy from the surroundings and transitions from a solid state to a liquid state. During this phase transition, the ice molecules gain enough energy to break their rigid crystal structure and form a more fluid arrangement, resulting in the formation of liquid water. The amount of heat energy required to convert a given quantity of ice to water at 0°C is known as the heat of fusion.
