Why mercury is preferred as a thermometric substance?

Answer 1

Reason1.The Mercury is good conductor of heat and expand rapidly and thus the temp;change quickly.

2.Mercury has a low heat capacity

3.The mercury is opeque to light and can been seen clearly

4.The mercury does not stick with the wall of container.

5.Mercury has a freezing point of -39c and boiling point of 357

Answer 2

Well, friend, mercury is often chosen as a thermometric substance because it has a wide range of temperature measurement, remains in liquid form over a large temperature range, and has a high coefficient of thermal expansion. Its shiny surface also makes it easy to see the level of the liquid in the thermometer, allowing for accurate readings. Just like painting a happy little tree, choosing mercury can help us create a more precise and reliable way to measure temperature.

Answer 3

Mercury is preferred as a thermometric substance because of its high thermal expansion, which makes it sensitive to temperature changes. It also has a wide range of operation (-39°C to 357°C) and is a good conductor of heat, allowing for quick response to temperature changes. Additionally, mercury is stable, non-wettable to glass, and easily visible in the thermometer.
