Quizplus · Accepted Answer

Water has the highest heat transfer coefficient among the quenching mediums listed, meaning it can absorb and remove heat from a part more quickly than the other options. This results in a more rapid cooling of the part, which can be beneficial for the desired material properties. However, it is important to note that water quenching can also lead to more severe distortion and cracking compared to other methods.
