Question

Why do we prefer to use Mercury thermometer over alcohol thermometer

Answer 1

Answer:

Hello mate...........⚘

Explanation:

Mercury is the only one in liquid state at room temperature. It's used in thermometers because it has high coefficient of expansion. Hence, the slightest change in temperature is notable when it's used in a thermometer. It also has a high boiling point which makes it very suitable to measure higher temperatures.

It is more durable than alcohol thermometer because mercury does not evaporate easily. It is smaller in size as compared to alcohol one. Mercury does not wet the wall of the thermometer, which means that results can be highly accurate
