What astronomer created a mercury thermometer which showed water freezing at 0 degrees and boiling at 100 degrees?
Anders Celsius
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.
How did Celsius come about?
Celsius was invented as a way of measuring temperature. A scientist named Anders Celsius put a thermometer in water until it froze, and marked where the mercury level was. He then measured the level in boiling water. The temperature in boiling water was given 100 Celsius, freezing was given 0 Celsius.
How does Anders Celsius'e thermometer work?
Anders Celsius' thermometer works based on the principle that liquids expand when heated and contract when cooled. The mercury or alcohol inside the thermometer rises or falls in a calibrated tube to indicate changes in temperature. Celsius defined the scale so that 0 degrees represents the freezing point of water and 100 degrees represents the boiling point of water.
What was Anders Celsius famous for?
Anders Celsius was famous for developing the Celsius temperature scale, which is now widely used as the standard measurement system for temperature in most countries around the world. He created the scale in 1742, with 0 degrees as the freezing point of water and 100 degrees as the boiling point of water at sea level.
Anders Celsius invention?
Anders Celsius invented the Celsius temperature scale in 1742, using 0 as the freezing point of water and 100 as the boiling point. This scale is widely used in scientific and everyday applications around the world.
You are trying to calibrate a celsius thermometer. when you place the thermometer into a beaker of boiling water what should the thermometer read?
The thermometer should read 100 degrees Celsius when placed in boiling water at standard atmospheric pressure.
What is the boiling point of water in degrees Celsius on a thermometer?
The boiling point of water is 100 degrees Celsius and the melting point of water is 0 degrees Celsius
How did Anders Celsius invent the Celsius thermometer?
He used the "degree" as the unit of temperature. He based his standards for comparison on the properties of water, the most abundant liquid on Earth. Celsius assigned zero degrees to the temperature at which ice melts at sea level. He assigned a value of one hundred degrees to the temperature at which liquid water boils at sea level. Then he separated the region between these temperatures into 100 evenly spaced units or degrees.
What inventions did Anders Celsius invent?
Anders Celsius is known for inventing the Celsius temperature scale in 1742. The Celsius scale is based on dividing the boiling point and freezing point of water by 100 degrees. Celsius's temperature scale is widely used around the world today.
Did Andres Celsius invent or improve the thermometer?
Swedish scientist Anders Celsius neither invented nor improved the thermometer. What he did, in 1742, was to propose a thermomenter scale with 100 divisions between water's boiling point and its freezing point. The scale developed by Celsius was actually the reverse of the scale we use today. He placed 0 at water's boiling point and 100 at its freezing point. So the Celsius temperature scale was not actually his "invention"; it is simply named in his honor.
What type of thermometer is used in the metric system?
If you mean "what temperature scale" it is Celsius (C). The scale is based upon the freezing and boiling points of pure water at sea level. Water freezes at 0 C and boils at 100 C. It is named after Swedish astronomer Anders Celsius.
