Usage Notes
When used literally, "蒸発" is a neutral scientific term. In everyday conversation, the figurative use to describe someone disappearing is informal and often dramatic. Be careful not to confuse "蒸発" with "消える" (to disappear) as "蒸発" implies a sudden and complete vanishing, often without explanation.
