Who is Mercury the only metal to have been used in thermometers?
Mercury is the only metal traditionally used in thermometers due to its unique properties, such as a consistent expansion and contraction with temperature changes, which allows for accurate measurements. It remains liquid at a wide range of temperatures, from -38.83°C to 356.73°C, making it ideal for measuring both high and low temperatures. Additionally, mercury's high density and low surface tension help it to rise smoothly within the thermometer tube, providing clear readings. However, due to health and environmental concerns, many modern thermometers now use alternative substances.
Why was this thermometer made to measure only temperatures in this narrow range?

Why wouldn't you take a mercury in glass thermometer with you to south pole?
If I only had those 2 choices... I would use ALCOHOL since Mercury freezes at -38.72° Celsius. The North Pole can get down below -50° Celsius. Ethanol (alcohol) freezes at -114 ° Celsius Methanol (alcohol) freezes at -97.8° Celsius
Are there metals in liquid state name them?
Mercury is the only metal that is a liquid at room temperature, despite it's high density.
The only metal that's a liquid at ordinary temperatures ordinary for earth that is not a hotter planet?
Mercury.
What liquid metal is most commonly used in thermometer?
The liquid metal in many thermometer is mercury (Hg).
Do farmers use mercury?
only in a thermometer
What is the range measured by Mercury thermometer?
Mercury freezes at -38.83 °C (-37.89 °F) so it can only be used at temperatures higher than this.
How mercury rises in thermometer by rising temp?
The mercury in the thermometer's tube expands and contracts due to the surrounding temperature. As the mercury is inside a narrow tube, it can only expand upwards, and contract downwards.

How did Mercury's location in the solar system affect its composition?
Mercury is rich in metals because only metallic grains could survive the high temperatures so near the Sun.
What is the mercury in the thermometer?
The Mercury expands with temperature. Since expansion is linear over the normal range of a mercury-driven thermometer, the level of mercury within a little glass tube indicates the current temperature of the thermometer's immediate environment.
Is mercury expanding in a thermometer a chemical or physical change?
Physical. The mercury doesn't change.
Why should you use only mercury in thermometer?
Actually, you should NOT. Mercury is very toxic.
Why are decimals used on thermometer?
To measure temperatures to an accuracy greater than only whole degrees.
Why is mercury and alcohol used in thermometer?
Mercury is the only metal that remains liquid at room temperature and it expands and contracts evenly over a large temperature range of -40to +300 degrees. Unfortunately it is toxic when the thermometer breaks and so alcohol is replacing Mercury for every day -10 to 100degree C thermometers as used in school labs. Electronic temperature sensors,like thermocouples, are taking over for higher temperatures.
Why does the mercury move up and down the scale as the temperature changes?
Mercury expands and contracts in response to temperature changes, causing it to rise or fall in the thermometer's tube. When the temperature increases, the mercury expands and moves up the scale, and when the temperature decreases, the mercury contracts and moves down the scale.
