During the process of "flashing," refrigerant undergoes a phase change from a liquid to a gas. This occurs when the liquid refrigerant is subjected to a decrease in pressure, which leads to a rapid change in state. As the refrigerant absorbs heat from its surroundings during this transition, it vaporizes and becomes a gas. This is a crucial concept in refrigeration systems, as it demonstrates how refrigerants move through different states to absorb and release heat, ultimately contributing to the cooling cycle.

In contrast, other options present different scenarios not relevant to the flashing process. For example, turning into a liquid describes the condensation process, while cooling without a phase change refers to sensible heat transfer. Finally, condensing and releasing heat pertains to the process of vapor turning back into liquid, which is independent of flashing. Understanding flashing is essential for effective refrigeration system management as it impacts efficiency and overall performance.
