Which statement is true regarding the change of state in matter?

The statement regarding heat causing a change of state without raising the temperature is accurate due to the concept of latent heat. When a substance undergoes a phase change, such as melting or boiling, heat energy is either absorbed or released, but the temperature of the substance does not change during the transition. For example, when ice melts at 0 degrees Celsius, it absorbs heat but remains at that temperature until all the ice has turned to water. This phenomenon demonstrates that heat can facilitate a change of state while the temperature remains constant.

In contrast, the other options present misconceptions about the behavior of matter in different states. The notion that liquids cannot turn into gas at any temperature is incorrect, as liquids will evaporate at various temperatures, even below their boiling point. The idea that a solid cannot become a liquid overlooks the fundamental principle of melting, which occurs when solids are heated to their melting point. Lastly, while many changes of state are reversible (e.g., ice melting and then refreezing), many are not reversible under ordinary circumstances, such as the burning of wood. Thus, the accurate understanding of heat and changes in states of matter supports the correctness of the selected statement.
