Mercury has a high coefficient of expansion, which means it expands and contracts significantly with temperature changes, making it very sensitive to even small temperature variations. It remains a liquid at a wide range of temperatures (-39°F to 675°F), making it suitable for measuring both high and low temperatures accurately. Mercury is also a good conductor of heat, allowing for quick response times in temperature measurements.

Why should not use water in the thermometer?
Water can damage the internal components of the thermometer, potentially causing it to malfunction or become inaccurate. Water can also introduce impurities or microbes that may affect the accuracy of the readings. It's best to follow the manufacturer's instructions and use the appropriate cleaning methods recommended for the specific type of thermometer.
Are alcohol thermometers better than mercury thermometers?
Both alcohol and mercury thermometers are effective for measuring temperature, but alcohol thermometers are generally safer to use due to the toxicity of mercury. However, mercury thermometers provide more accurate readings at higher temperatures compared to alcohol thermometers.
What property of half-lives makes radioactive material so problematic?
The property of half-lives that makes radioactive material problematic is that they can remain dangerous for long periods of time. This means that even after a substantial amount of time has passed, the material can still emit radiation and pose a threat to human health and the environment.
Is mercury explosive?
Mercury is not explosive. It is a heavy, silvery metal that is liquid at room temperature and not reactive enough to explode under normal conditions. However, mercury can create toxic vapors when heated, so handling it with caution is important.
Why mercury is preferred as a thermometric substance?
Reason1.The mercury is good conductor of heat and expand rapidly and thus the temp;change quickly. 2.Mercury has a low heat capacity3.The mercury is opeque to light and can been seen clearly4.The mercury does not stick with the wall of container.5.Mercury has a freezing point of -39c and boiling point of 357
What is the boiling point of the thermometer?
The boiling point of a thermometer depends on the type of liquid inside. For traditional mercury thermometers, the boiling point is around 356.7°C (674.1°F). Digital thermometers with different liquids may have varying boiling points.
Why isn't mercury in thermometers any more?
Mercury is no longer used in thermometers due to its toxicity and potential health risks. When broken, mercury can release toxic vapors that can be harmful if inhaled or ingested. As a result, alternative materials, such as alcohol or digital sensors, are now used in thermometers.
What makes mercury special that it can be used in a thermometer?
Mercury is a heavy metal also known as QUICKSILVER it is special because it is in a form of liquid
What makes mercury go up and down a thermometer?
the heat and temperature that causes it to rise and fall.
What makes mercury in a thermometer go up and down?
Change in temperature is what cause the Mercury to expand up (hotter) or shrink down (colder).
What makes mercury so special it can be used in a thermometer?
Mercury is a heavy metal also known as QUICKSILVER it is special because it is in a form of liquid
Explain how a deformation thermometer measures temperature?
A deformation thermometer measures temperature by using materials that change shape with temperature variations. As the temperature increases, the material expands or contracts, causing a mechanical deformation. This change in shape is then converted into a temperature reading based on the known relationship between the material's deformation and temperature.
Why is mercury used in a thermometer why not green water?
Water does not change as much in volume with temperature as much as Mercury does, which makes it more difficult to read temperature Changes on a scale.
Why do we jerk a clinical thermometer?
We jerk a clinical thermometer to ensure that the mercury or alcohol inside is at the lowest point on the scale before use. This makes sure that we get an accurate measurement of body temperature when placed in the mouth, under the arm, or in the rectum. Jerking the thermometer helps to reset the mercury column to the starting position for a new reading.
What is mercury's mass made of?
It is made up of the material which makes up the planet.
What property of glass makes it a good material for windows?
you use salt
Which property makes it difficult for electricity to pass through a material?
density
