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.

Where a thermometer should be kept in determining melting point of ice?
fordetermining point of ice,the thermometer should be kept
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.
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 is the sub discipline of determining the melting point of lead?
The melting point of lead is 327,46 0C.
How fast do you heat the sample when determining a melting point?
The apparatus used for determining the melting point will heat the sample at an appropriate rate. All you need to do is watch and note the point at which the sample melts, as should be demonstrated to you by your lab supervisor.
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.
Where a thermometer should be kept in determining melting point of ice?
fordetermining point of ice,the thermometer should be kept
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.
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
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.
General statement can you make about degrees Fahrenheit and Celsius?
1. The degrees are of different sizes. 2. The lower fixed point of Celsius is the freezing point of water, that of Fahrenheit is lower. Likewise the upper fixed point of Fahrenheit is quite low, but that of Celsius is higher, at the boiling point of water.
If you heat too fast when determining melting point will you observe a lower or higher melting point than true value?
you will observe no difference in it.
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.
Which thermometer is most suitable for measuring boiling point of water mercury or alcholic thermometer?
Which thermometer is most suitable for measuring boiling point of water mercury or alcoholic thermometer
What is the most suitable thermometer for measuring boiling point of water?
- a thermometer with mercury - a thermometer with thermoresistance
