An ethanol thermometer would be better suited for use in the arctic compared to a Mercury thermometer. This is because ethanol has a lower freezing point (-114°C) compared to mercury (-39°C), making it more reliable in extremely cold temperatures. Additionally, ethanol is safer to use as it is non-toxic in case of breakage.

What color is the Mercury in a Mercury thermometer?
Mercury in a Mercury thermometer is typically silver in color.
The liquid most commonly used in a thermometer is either mercury or?
alcohol, such as ethanol or dyed ethyl alcohol. Mercury and alcohol are both used in thermometers due to their ability to expand and contract with temperature changes, allowing accurate measurement of thermal fluctuations. Mercury is less common now due to its toxicity.
Can the mercury in a thermometer hurt you?
Yes, if a mercury thermometer breaks, the mercury can vaporize and be inhaled, which can be harmful to your health. It is important to handle and dispose of a broken mercury thermometer properly to avoid exposure to mercury.
What causes mercury in a thermometer to rise?
The mercury in a thermometer rises because of thermal expansion. When the temperature surrounding the thermometer increases, the molecules of the mercury expand, causing it to move up the narrow tube of the thermometer.
What is the most dangerous thermometer if it breaks?
A mercury thermometer is the most dangerous if it breaks because mercury is a toxic substance that can harm human health and the environment. If a mercury thermometer breaks, it is important to follow proper cleanup procedures to avoid exposure to the mercury.
Would ethanol be better than mercury for an outdoor thermometer in the arctic?
Ethanol would be better than mercury for an outdoor thermometer in the Arctic because ethanol has a lower freezing point than mercury, making it more reliable in extremely cold temperatures. Additionally, ethanol is less toxic than mercury, which is important for environmental and safety reasons in outdoor settings.
What are the materials in a thermometer?
For a classic thermometer: glass and mercury, colored ethanol or another liquid.
What are the two substances used in a liquid column thermometer?
The two substances used in a liquid column thermometer are mercury and alcohol. Mercury thermometers use mercury as the liquid inside the glass tube, while alcohol thermometers use colored alcohol such as ethanol or dyed ethanol.
What is the name of the liquid in a thermometer?
The red liquid in a liquid-in-glass thermometer is mineral spirits or ethanol alcohol mixed with red dye. A grey or silver liquid inside the thermometer is mercury. Mercury thermometers are not used anymore due to the dangers associated with mercury.
Why is alcohol found in the school's thermometer instead of mercury?
Because the thermal expansion is higher from alcohol (ethanol) and then it's more precise.
What color is the Mercury in a Mercury thermometer?
Mercury in a Mercury thermometer is typically silver in color.
What is the red stuff in a thermometer?
The red liquid in a thermometer is typically mercury. Mercury is used because it expands and contracts uniformly with changes in temperature, allowing for accurate temperature readings. However, due to the toxicity of mercury, many modern thermometers use safer alternatives like alcohol or digital sensors.
What is in a thermometer besides Mercury?
Some thermometers use alcohol or dyed alcohols like ethanol instead of mercury. These liquids expand and contract with temperature changes, allowing the thermometer to measure the temperature. Digital thermometers use electronic sensors to measure temperature.
The liquid most commonly used in a thermometer is either mercury or?

What is the clear liquid inside a Galileo thermometer?
The clear liquid inside a Galileo thermometer is typically a hydrocarbon-based liquid, such as ethanol or mineral oil. This liquid expands and contracts with temperature changes, causing the glass spheres with different densities to float or sink.
Can the mercury in a thermometer hurt you?
Yes, if a mercury thermometer breaks, the mercury can vaporize and be inhaled, which can be harmful to your health. It is important to handle and dispose of a broken mercury thermometer properly to avoid exposure to mercury.
Will mercury float in ethanol?
No, mercury is denser than ethanol, so it will sink and not float.
