WebbAlcohol, which is used as a thermometric liquid, has the following characteristic properties : 1. Alcohol has a very low freezing point of about −112 o C and hence is suitable in thermometers to record very low temperatures. 2. Alcohol has a low boiling point of about 78 o C and therefore cannot be used to measure high temperatures. 3. The boiling point of water is 100 degrees. This definition assumes pure water at a specific pressure chosen to approximate the natural air pressure at sea level. Thus an increment of 1 °C equals 1 100 of the temperature difference between the melting and boiling points.
