Correct Answer

D

Explanation

One special advantage of alcohol over mercury as a thermometric liquid is its safety. Mercury is a hazardous substance that can be harmful to human health and the environment. When a mercury thermometer breaks, it releases toxic mercury vapor, which can be inhaled and cause poisoning. Additionally, the disposal of mercury-containing thermometers must be carefully managed to prevent environmental contamination.

Alcohol, on the other hand, is a much safer alternative for use in thermometers. It is not toxic, and its fumes are not harmful when inhaled. This makes alcohol thermometers safer for both the user and the environment. They are also easier to dispose of, as they do not pose the same environmental risks as mercury. For these reasons, alcohol thermometers are often preferred in situations where safety is a primary concern, such as in schools, laboratories, and healthcare settings.
