How do you verify ice point of mercury thermometer?
To verify the ice point of a mercury thermometer, place the thermometer in a mixture of crushed ice and water, stirring gently. Allow the thermometer to stabilize for a few minutes, ensuring the mercury column remains constant. The temperature indicated by the thermometer should match the expected ice point of 0°C (32°F).
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.
Why mercury used in minimum thermometer?
Mercury is used in minimum thermometers because it has a low freezing point (-38.8°C) and a high coefficient of expansion, making it sensitive to small temperature changes. This allows the thermometer to accurately measure and record the lowest temperature reached during a specific period.
What is the starting point of the thermometer?
The starting point of a thermometer is typically the lowest end of the temperature scale, which is usually labeled as 0 degrees Celsius or 32 degrees Fahrenheit, depending on the type of thermometer.
What is the lowest temperature on a thermometer?
The lowest temperature on a standard mercury thermometer is typically around -40 degrees Celsius or Fahrenheit, depending on the specific model. Some digital thermometers can register even lower temperatures.

Which metal has lowest boiling point?
Mercury Hg -38.8' Now you could consider Hydrogen to be a metal if you are willing to get creative with the definition of metal. In that case it would be −259.16 °C

What is the boiling point of the thermometer?
The question to ask is: What is the boiling point of mercury (as mercury is the substance within a thermometer, unless of course you are referring to the material that makes up the thermometer itself).You can simply google that.But...it's 356.7° C
What color is the Mercury in a Mercury thermometer?
Mercury in a Mercury thermometer is typically silver in color.
What is the application of a Six's thermometer?
A Six's thermometer is typically used in meteorology to measure the minimum and maximum temperatures over a period of time. It consists of two mercury columns that are moved by the mercury in the thermometer to indicate the highest and lowest temperatures reached.
How cold would it have to be in order to freeze a mercury thermometer?
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.
