u don't have to flick the thermometer to reset the temperature reading when you use an alcohol based thermometer (unlike a mercury thermometer where you have to flick and flick and flick flick flick that thermometer for the mercury to be reset so that you can make an accurate reading) a disadvantage is that the alcohol thermometer is slightly less acurate The biggest advantage is that alcohol is not nearly as toxic as mercury, so that if the thermometer breaks, you won't be poisoned.
We still use colored alcohol for our liquid in everyday thermometers.
The liquid in a clinical thermometer is often mercury. But there are thermometers that use a coloured alcohol.
Rubbing alcohol is a good liquid to use in a simple thermometer because it expands when heat ia added to it. When cold temperatures are added to it, it regroupes.
The colour makes the alcohol easier to see inside the thin glass thermometer.
alcohol thermometer is used to measure very low temperature.i.e.-112*c
