Answer

Difference between mercury and alcohol as a thermometric substance
Mercury Alcohol
1. It is non-volatile It is volatile
2. It has uniform expansion It has non-uniform expansion
3. It is opaque making it easier to read the thermometer It is transparent thus making it difficult to read the thermometer
4. It has a low coefficient of expansion It has a high coefficient of expansion
5. It has a high boiling point so it can be used to measure high temperatures It has a low boiling point so it cannot be used to measure high temperatures
