What is the purpose of Mercury in a Thermometer?
Mercury in a thermometer is used because it has a high coefficient of expansion, meaning it expands and contracts in response to temperature changes. This property allows for accurate measurement of temperature as the mercury level rises and falls inside the thermometer. Additionally, mercury has a wide temperature range in which it remains a liquid, making it suitable for measuring a broad range of temperatures.
A is a thin glass tube with a bulb on the one end that contains liquid usually mercury or colored alcohol?
A is a thermometer used for measuring temperature, typically with mercury or colored alcohol as the measuring fluid. The liquid expands or contracts based on temperature changes, providing a reading on the scale of the thermometer.
How does a thermometer indicate the temperature of an object?
A thermometer measures temperature by using a material that expands or contracts with changes in temperature. This material is usually mercury or alcohol. As the temperature of the object being measured changes, the material in the thermometer expands or contracts, causing the level to rise or fall on a scale, indicating the temperature.
Who made the first mercury thermometer?
Galileo invented an air thermometer in about 1600, but changes in atmospheric pressure made accurate measurement difficult. Liquids were quickly used instead and Gabriel Fahrenheit was the first to use alcohol (1709) and mercury (1714), in a thermometer.
Astronomer who created a mercury thermometer which showed water freezing at 0 degrees and boiling at 100 degrees?
Anders Celsius, a Swedish astronomer, created a mercury thermometer that had water freezing at 0 degrees and boiling at 100 degrees. This eventually led to the establishment of the Celsius temperature scale widely used today.
What is the purpose of a mercury thermometer?
to see what is the temperature The Mercury expands or contracts depending on the temperature so its height against the scale on the thermometer tells you the temperature.
Is mercury used in food thermometer?
In a mercury thermometer, a glass tube is filled with mercury and a standard temperature scale is marked on the tube. With changes in temperature, the mercury expands and contracts, and the temperature can be read from the scale. Mercury thermometers can be used to determine body, liquid, and vapor temperature.
Astronomer who created a mercury thermometer?
In 1714, Gabriel Fahrenheit invented the first mercury thermometer.......The Celsius scale, invented by Swedish Astronomer Anders Celsius (1701-1744)
How does mercury work in a thermometer to measure temperature accurately?
Mercury in a thermometer expands and contracts with changes in temperature. As the temperature rises, the mercury expands and rises in the tube, and as the temperature falls, the mercury contracts and lowers in the tube. This movement is then converted into a temperature reading on the scale of the thermometer, allowing for accurate temperature measurement.
What happen to the mercury in a thermometer when the temperature increase?
When the temperature increases, the mercury in a thermometer expands and rises up the column because the volume of the liquid increases with temperature. This expansion is linear and is used to indicate the rise in temperature on the thermometer scale.
In what year was the mercury thermometer invented?
The mercury thermometer with a standardized scale was invented in the year 1714 by a German physicist by the name of Gabriel Fahrenheit. And the standardized temperature scale was introduced by him later in 1724.
How does a mercury thermometer work to measure temperature?
A mercury thermometer works by using the expansion and contraction of mercury in response to temperature changes. As the temperature rises, the mercury expands and rises up the narrow tube, indicating a higher temperature. Conversely, as the temperature decreases, the mercury contracts and lowers in the tube, showing a lower temperature. The temperature is read by looking at the level of the mercury in the tube against a scale marked on the thermometer.
What did Gabriel Fahrenheit invent?
The Fahrenheit system of temperature measurement. Actually he invented the thermometer.
What happen to the thermometer reading when the temperature increase?
When the temperature increases, the mercury inside the thermometer expands due to thermal expansion, causing the level of mercury to rise in the thermometer tube. This results in a higher reading on the scale of the thermometer, indicating a higher temperature.
What is a variable in a thermometer?
In a thermometer, a variable is the temperature being measured. Thermometers detect changes in temperature by expanding or contracting a substance, such as mercury or alcohol, which then indicates the temperature on a scale.
Who invented the mercury themometer?
The mercury thermometer was invented by Daniel Gabriel Fahrenheit. He had invented an alcohol thermometer years earlier. In 1724, he introduced the Fahrenheit temperature scale.
What is the diffrerence between digital thermometer and mercury thermometer?
A digital thermometer uses electronic sensors to measure temperature and displays the reading digitally, while a mercury thermometer uses a column of mercury to measure temperature and has a calibrated scale to indicate the temperature. Digital thermometers are often faster and more accurate than mercury thermometers, and are also safer since they do not contain mercury.
