Alcohol thermometers are used rather than mercury thermometers in very cold regions because alcohol has a lower freezing point than mercury. Pure ethanol freezes at -115 degrees C, while mercury freezes at -38 degrees C.

Answer:
An alcohol thermometer cannot measure the temperature of boiling water because it is only capable of measuring temperatures up to 80°C.
Explanation:
A thermometer is a device used to determine the temperature or temperature gradient.
Let's see the following points.
- At 80°C, the alcohol begins to boil.
- Boiling water has a temperature of 100°C, while an alcohol thermometer can only measure up to 80°C.
- As a result, an alcohol thermometer cannot measure the temperature of boiling water because it is only capable of measuring temperatures up to 80°C.
