Description of alcohol thermometer
The alcohol thermometer is a thermometer made by using the thermal expansion and contraction properties of alcohol. Under 1 standard atmosphere, the highest temperature that an alcohol thermometer can measure is generally 78°C. Because alcohol has a boiling point of 78°C at 1 standard atmosphere. However, the pressure in the thermometer is generally higher than 1 standard atmosphere, so some alcohol thermometers have a range greater than 78 degrees.
