What are the Kelvin and Celsius temperature scales?
The Celsius scale sets the freezing point of water as zero degrees and the boiling point of water as 100 degrees (hence its alternative name of the centigrade scale). The Kelvin scale sets as zero the temperature at which an ideal gas would have a volume of zero, and all thermal motion ceases, so it is sometimes called absolute zero. The other fixed point is then the triple point of water, which is set at 273.16 K. The divisions of the two scales have the same magnitude.
How Will You Calibrate a thermometer in degree Celsius.. ..?
The thermometer was used by the originators of the Fahrenheit and Celsius scales.Anders Celsius, a Swedish Astronomer, devised the Celsius scale, which was described in his publication the origin of the Celsius temperature scale in 1742.Celsius used two fixed points in his scale: the temperature of melting ice and the temperature of boiling water. This wasn't a new idea, sinceIsaac Newton was already working on something similar. The distinction of Celsius was to use the melting temperature and not the freezing temperature. The experiments for reaching a good calibration of his thermometer lasted for 2 winters. By performing the same experiment over and over again, he discovered that ice always melted at the same calibration mark on the thermometer. He found a similar fixed point in the calibration of boiling water vapour (when this is done to high precision, a variation will be seen with atmospheric pressure). At the moment that he removed the thermometer from the vapour, the mercury level climbed slightly. This was related to the rapid cooling (and contraction) of the glass.The air pressure influences the boiling point of water. Celsius claimed that the level of the mercury in boiling water is proportional to the height of the barometer.When Celsius decided to use his own temperature scale, he originally defined his scale "upside-down", i.e. he chose to set the boiling point of pure water at 0 °C (212 °F) and the freezing point at 100 °C (32 °F).[1] One year later Frenchman Jean Pierre Cristin proposed to invert the scale with the freezing point at 0 °C (32 °F) and the boiling point at 100 °C (212 °F). He named it Centigrade.[2]Finally, Celsius proposed a method of calibrating a thermometer:Place the cylinder of the thermometer in melting pure water and mark the point where the fluid in the thermometer stabilises. This point is the freeze/thaw point of water.In the same manner mark the point where the fluid stabilises when the thermometer is placed in boiling water vapour.Divide the length between the two marks into 100 equal pieces.These points are adequate for approximate calibration but both vary with atmospheric pressure. Nowadays, the triple point of water is used instead (the triple point occurs at 273.16 kelvins (K), 0.01 °C).
-273.15 celsius is the temperature of absolute zero?
Absolute zero is 0 degrees Kelvin, -273.15 degrees Celsius, and −459.67 degrees Fahrenheit. Short answer: No. Technically, absolute zero could be defined to be whatever number you wanted on some arbitrary scale. However, on the two commonly used scales - Fahrenheit & Celsius - 273.15 is not absolute zero. I'm guessing that you actually meant -273.15. On the Celsius scale, this is absolute zero (to 5 significant figures).
What are the fixed points on the scale?
The two fixed points on the Celsius scale are the boiling point and the freezing point of water at sea level. Boiling point- 212◦C, freezing point- 32◦C.HOPE THIS HELPED ^-^
Who built a thermometer based not one but two fixed points?
The Celsius scale is based on two fixed points: The freezing point of water at 0 degrees, and the boiling point of water at 100 degrees.
What is the temperature taken as lower fixed point in Celsius scale?
The two main fixed points in the Celsius scale are: Zero degrees the freezing point of water and 100 degrees its boiling point. Any temperature below freezing are minus values, the lowest being -273 degrees absolute zero the point where everything stops.
Why fixed points are needed before a temperature scale is marked on a thermometer?
Generally two fixes points,Tof pure melting ice and T of steam of water boiling at one atomospheric pressure.are needed to build a standard degree of coldness and hotness. So that there will be a range of T to set the scale.
What are the upper fixed point in Celsius?
The two fixed points on the Celsius scale are the boiling point and the freezing point of water at sea level. Boiling point- 212◦C, freezing point- 32◦C.HOPE THIS HELPED ^-^
How do you spell degrees?
The metric system temperature scale is spelled "Celsius" (capitalized, named after the Swedish astronomer Anders Celsius).The name of the temperature scale is Celsius, named for its inventor Anders Celsius.The likely word is the proper noun Celsius, a centigrade temperature scale named for Swedish scientist Anders Celsius.
How do you use Celsius in a sentence?
Zero degrees on the Celsius scale equals thirty two degrees on the Fahrenheit scale.
What are the names of the two scales to measure temperature?
Kelvin scale Celsius scale Fahrenheit scale
Why would someone invent the Celsius temperature scale?
It has two natural fixed points: 0 degrees at the freezing point of water and 100 degrees at the boiling point of water. The range is divided into 100, in line with other decimal based scales. This is in contrast to the previously widely used Fahrenheit scale whose zero point is somewhat arbitrary.

What is the temperature of 48F when converted to the Celsius scale?
It is: 8.89 degrees Celsius rounded to two decimal places
What is the set of two fixed points and all points in between them?
It is a line segment.
