Yes, antifreeze can evaporate under certain conditions. The rate at which antifreeze evaporates depends on various factors, such as temperature, humidity, and the surface area of the liquid. At higher temperatures and lower humidity, antifreeze can evaporate more quickly. In addition, if the antifreeze is exposed to air or has a large surface area, it can also evaporate more rapidly. It is important to note that inhaling antifreeze vapors can be harmful to human health, so it is important to handle it with care and in a well-ventilated area.
