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 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.
Why water is not used in thermometer?
Well, Mercury can't freeze or evaporate at the temperature recorded on a standard thermometer. If water were used in a thermometer, we wouldn't be able to record any temperatures below its freezing point (0 degrees Celsius) or above its boiling point (100 degrees Celsius. Mercury has many unique properties. It is a liquid metal and as a metal it expands when heated. When the mercury is heated it rises in the thermometer. And markings on the glass indicate the temperature. Water does not do this. But now in this Digital World mercury has been loosing its importance just because everyone wants to use Digital Technology which provide fast and accurate reading and also safe in use, no doubt mercury provides an accurate reading of temperature but it is not fast and safe as compared to Digital Thermometer.
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.
What is the fixed point on a lever that does not move?
The fulcrum is the fixed part of a lever. (the pivot point)
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.
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.
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.
How do you check grill temperature of split ac?
Temperature major through a thermometer, one is contact type thermometer another one non contact type.Non contact type thermometer known as laser thermometer. With non contact type thermometer or leaser thermometer you will read out temperature from a particular long distance without contact the particular point which temperature want to know.Contact type thermometers are glass type thermometers, analogue or digital read out type. Digital thermometer and analogue dial read out type thermometer have a sensor and that sensors must be to touch hot or cold point to read the temperature.Best use of contact type thermometer is uses full in a closed area. To know grill temperature of a slip Air Condition best use nonContact thermometer to read exact temperature.
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
