Why is a clinical thermometer made to measure in only temperatures in this lower range?
A clinical thermometer - is designed to measure typical human temperatures. The 'normal' temperature of a human is 37 C (98.4 F). There's no point in using a thermometer that can measure a huge range - when human temperatures fall within a very narrow range.
Why are the temperatures of the melting point of ice boiling point of water called fixed point in calibrating the thermometer?
it is because they were consistent at melting and boiling point
Why is it more important to have constriction in a clinical thermometer than in a laboratory one?
It stays at the maximum point so you get an accurate reading
Why does a clinical thermometer not start with at 0 while some lab thermometer even start at -5 degrees celsius?
clinical thermometers use alcohol while lab thermometers use mercury,while alcohol has a freezing point of -112 o c mercury has freezing point of -39 o c
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.
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.
Why do you use pure ice in determining a lower fixed point of a thermometer?
If ice contains any other dissolved material, the freezing point of the mixture would be lower than the freezing point of pure water or ice.

Why is a clinical thermometer usually shaken after use?
Well, a clinical thermometer is shook after use so that the mercury comes back to its initial point i.e. where it had been before the temperature was taken.
What is lower fixed point?
upper fixed point is a temperature of stem from water boiling and standards atmospheric pressure lower fixed point is the temperature of pure melting ice.

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 will the mercury thermometer show when it is kept in ice?
The question must be asked carefully. If the thermometer is in water ice and there is no liquid water, and there is one atmosphere of pressure, the thermometer can read anything from the freezing point of water and lower, depending on the range of the thermometer. If the thermometer is in a stable mix of water and ice, it will read the freezing point of water.
Why can't and alcohol thermometer be used to measure the boiling point of water?
Because the boiling point of alcohol is lower than the boiling point of water.
