Mercury has a larger coefficient of expansion compared to water, which makes it more sensitive to changes in temperature. This allows for more precise measurement of temperature variations. Additionally, mercury does not adhere to glass surfaces, allowing for easy reading of the temperature scale.
Mercury freezes at -38.83°C (-37.89°F). In order to freeze a mercury thermometer, the temperature would have to be lower than this point. However, prolonged exposure to temperatures below freezing may damage the thermometer.
Yes, it is dangerous if mercury from a broken thermometer enters your pool. Mercury is a toxic substance that can be harmful if ingested or inhaled, and it can contaminate the water in your pool. It is important to contact a professional to safely clean and remove the mercury from the pool.
No, even if glass and mercury expanded at the same rates, a common mercury thermometer would not be feasible because the volume of mercury would still change non-linearly with temperature due to its high thermal expansion coefficient. This would result in inaccurate temperature measurements.
If surrounding water temperature is lower than the water in the thermometer, heat will transfer from the water in the thermometer to the colder water causing the liquid in the thermometer to drop.
Alcohol is a safer choice for a thermometer liquid as it is not as toxic as mercury, making it safer for both human health and the environment. Mercury can be harmful if it leaks or is accidentally ingested, whereas alcohol is less harmful if exposed.
A mercury thermometer (but not a medical one!)
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.
It could be used to do this - it is capable of doing it. However, Mercury is poisonous and a mercury thermometer is made out of fragile glass. Thus the danger that the thermometer would break releasing mercury into the milk (which would be for a person to drink) means that a mercury thermomiter is not the temperature sensor to use in this instance.
An Alcohol thermometer would be the best as it is more sensitive than the mercury thermometer.
The thermometer would melt
because the mixture of ice and water has an equilibrium temperature of 0 C and thus it will be the first calibration system and making sure that thermometer is working properly. The thermometer will have better contact with the water than with lumps of ice and therefore adjust better to its temperature.
Mercury freezes at -38.83°C (-37.89°F). In order to freeze a mercury thermometer, the temperature would have to be lower than this point. However, prolonged exposure to temperatures below freezing may damage the thermometer.
Mercury freezes at around -39 degrees Celsius, so below this temperature, the mercury in the thermometer would solidify and no longer be able to expand and contract with changes in temperature, rendering the thermometer unusable.
A Mercury thermometer (but not a medical one!)
A digital thermometer with a range of up to 100 degrees Celsius and high accuracy would be most suitable for measuring the boiling point of water. It should be able to quickly and accurately display the temperature at which water boils, which is 100 degrees Celsius at sea level.
because it would turn to ice and alcohol wouldn't
