Why alchole thermometers is used in cold countries?
Alcohol thermometers are used in cold countries because alcohol has a lower freezing point compared to mercury, making it suitable for measuring low temperatures. This allows alcohol thermometers to accurately measure the cold temperatures experienced in these regions without the risk of freezing and breaking like mercury thermometers. Additionally, alcohol is less toxic than mercury, making it safer for both human health and the environment.
Why is alcohol used in thermometers?
Alcohol is used in thermometers because it has a low freezing point and a wide temperature range over which it remains a liquid, making it suitable for measuring a range of temperatures accurately. Additionally, alcohol is non-toxic and evaporates quickly, allowing for quick readings.
Compare the expansion of mercury with alcohol?
Mercury expands less with temperature changes compared to alcohol, which has a higher coefficient of thermal expansion. This means that alcohol is more sensitive to temperature changes and exhibits greater expansion and contraction when heated or cooled.
What is cold and there is low rainfall?
An example of a place that is cold and experiences low rainfall is a polar desert, such as Antarctica. These regions have extremely low precipitation levels due to the cold temperatures leading to minimal moisture in the air.
What two units of degeers are found on all thermometers?
The two units of degrees found on all thermometers are Celsius and Fahrenheit. These units are used to measure temperature and provide a reference point for understanding how hot or cold something is.

Who created the liquid in glass thermometer?
The two most common liquids used in glass thermometers are mercury and alcohol, both of which were created by M. Nature. Alcohol thermometers are, or were, used in extremely cold areas like the Yukon, where the temperature could be expected to drop lower than -40 in the winter (-40 is where mercury freezes, and it is also the only temperature that is exactly the same on both Fahrenheit and Celsius thermometers).
Why are alcohol thermometers preferred in cold countries?
Alcohol thermometers are preferred in cold countries because they have a lower freezing point compared to mercury thermometers, so they can accurately measure temperatures in colder conditions without freezing and causing damage. Additionally, alcohol thermometers are safer to use as they do not contain toxic mercury, which is important for environmental and health reasons.
Which is better mercury or alcohol thermometers for low temperature measurements?
Alcohol thermometers are generally better for low temperature measurements as they have a wider temperature range, reaching lower temperatures than mercury thermometers. Additionally, alcohol is less toxic than mercury, making it safer to use in certain applications.

How cold is -100 degrees celsius?
-100 degrees Celsius is extremely cold. It is 173.15 degrees below freezing (0 degrees Celsius) and well below the freezing point of water. This temperature is often found in extremely cold regions like Antarctica.
Is there any place tornadoes don't happen?
Yes. Tornadoes do not occur in extremely cold regions such as Antarctica.
What is an Extremely cold and dry ecosystem is called?
An extremely cold and dry ecosystem is called a polar desert. These regions have low temperatures and limited precipitation, leading to frozen conditions and minimal plant life. Examples include Antarctica and parts of the Arctic.
Why is alcohol used in thermometres?
Alcohol can be used in some thermometers due the fact of its very low freezing point. It may be used in cold atmospheres such as freezers. It however would not be suitable in vey hot atmostpheres due to the boiling point.
What kind of deserts do jackrabbits live in?
Jackrabbits live in nearly all deserts - hot tropical, cold winter, etc. They do not live in extremely hot and dry deserts that lack vegetation nor are they found in extremely cold regions.
Uses of alcohol thermometer?
Alcohol thermometers are commonly used in laboratory settings for measuring temperatures within a range of -115°C to 78°C. They are also used in medical applications, such as taking body temperature. Additionally, alcohol thermometers are used in industrial processes and food service to monitor temperature control.
Compare the expansion of mercury with alcohol?
Mercury expands less with temperature changes compared to alcohol, which has a higher coefficient of thermal expansion. This means that alcohol is more sensitive to temperature changes and exhibits greater expansion and contraction when heated or cooled.
