What are the two fixed points on the Celsius scale?
Zero and one hundred degrees: the freezing and boiling points of water respectively.
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).
Why the tube leading up from the bulb in a thermometer is very thin?
because its contain a silver mercury exactky fixed to it
What are the equal divisions between the two fixed points?
midpointbisection
Why upper fixed point and lower fixed point are not 100 degree celsius and 0 degree celsius respectively of pure water in kathmandu?
The boiling point of water is dependent upon air pressure, and in Nepal, the high altitiude results in low air pressure.
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 are the fixed reference points on the celsius thermometer?
If you have 2 then you are right. The freezing point of water and the boiling point of water are the 2 fixed points.
What determines the upper and lower fixed points of a thermometer?
Upper fixed point is the temperature of pure water boiling at normal atmospheric pressure.Lower fixed point is the temperature of a mixture of pure ice and pure water at normal atmospheric pressure. Each thermometer has a scale containing an upper and lower fixed points depending on the use of this thermometer for specific measurements.
The fixed points of water in celsius?
Water freezes at 0 degrees and boils at 100 degrees Celsius
What are the two fixed points on the Celsius scale?
Zero and one hundred degrees: the freezing and boiling points of water respectively.
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 ^-^
What does water have to do with measuring temperature?
The fixed points on the Celsius scale, for measuring temperature are based on the freezing and boiling points of water and, to that extent water is relevant to the measurement of temperature.

Is it true that Excel 2010 fixed references are referred to as relative reference?
No, they are called absolute references.
How you find fixed points of a function?
The fixed points of a function f(x) are the points where f(x)= x.
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 ^-^
