Question

why is mercury thermometer preferred over alcohol thermometer?​

Answer 1

Answer:

Mercury has a greater coefficient of thermal expansion than alcohol. This means a column of mercury will expand and rise more than a column of alcohol for the same temperature change. As a result, you can get finer readings with mercury. The three advantages of mercury are:

1. It expands uniformly when heated.

2. It has a high boiling point (357 °C) and a low freezing point (-39 °C).

3. It does not stick to the walls of the glass tube.
