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?
AnswerAlcohol 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. because of it's very low freezing point
Compare the expansion of mercury with alcohol?
Mercury expands more evenly than alcohol. This is why thermometers that contain mercury are more accurate than those that contain alcohol. However, alcohol freezes at a temperature much lower than mercury, so it is better used in thermometers in extreme cold conditions.
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 country has extremely cold winters and relatively mild summers?
Russia is known for having extremely cold winters, particularly in its northern regions and Siberia, where temperatures can drop to severe lows. In contrast, its summers are relatively mild, especially in the same regions, with temperatures that can be pleasantly warm but rarely reach extreme heat. Other countries with similar climates include Canada and parts of Scandinavia, such as Norway and Sweden.

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.
During winter, does the ocean freeze in certain regions"?
Yes, in some regions the ocean can freeze during winter, particularly in polar regions where temperatures are extremely cold.
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.
Uses of alcohol thermometer?
An alcohol thermometer is a liquid-in-glass thermometer which uses ethyl alcohol to gauge temperatures. The alcohol rises and falls as it contracts or expands when a change in temperature occurs.
Compare the expansion of mercury with alcohol?
Mercury expands more evenly than alcohol. This is why thermometers that contain mercury are more accurate than those that contain alcohol. However, alcohol freezes at a temperature much lower than mercury, so it is better used in thermometers in extreme cold conditions.
