How fast does an alcohol thermometer lose its accuracy?

An alcohol thermometer can lose its accuracy over time due to factors such as evaporation of the alcohol, expansion or contraction of the glass, and exposure to extreme temperatures. Typically, these thermometers can remain accurate for several years if handled properly and kept within their temperature range. However, frequent use or exposure to harsh conditions can accelerate the degradation of their accuracy. Regular calibration against a standard thermometer is advisable to ensure reliable readings.
