What is thermometer and how is used?
A thermometer is an instrument used to measure temperate. They can be used for outdoor purposes or to see if someone is running a fever. They are found virtually anywhere where temperature needs to be recorded.
What science was Charles cavendish famous for?
He invented the thermometer which recorded the maximum and minimum range measured.
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 alcohol used in a minimum thermometer?
Because of the freezing point of alcohol, temperatures down to minus 70C can be recorded
How does a thermometer work as a tool to measure thermal energy?
The first units of heat (Fahrenheit and Celsius) were created based on the thermometer. Not the other way around. That way, the thermometer would always be accurate. The thermometer works by putting a specific amount of mercury (a strange metallic substance) inside a tube of a specific volume. When the thermometer is heated, the mercury expands, pushing itself up the tube. The mark that it reaches is measured and recorded in degrees.

Why is it best to take temperature readings in the shade?
A thermometer is not kept in direct sunlight because the temperature needed to be recorded by the thermometer is of the air and not the rays of the sun.
How does the kink in a mercury or alcohol work in a clinical thermometer?
The kink stops the mercury from falling, giving the user/reader of the thermometer time to read the highest temperature recorded. Shaking the thermometer lets the mercury fall again.
Does digital thermometer has kink?
No need for such kink since the maximum temperature sensed could be recorded and can be seen at any time.
What is the highest temperature british Columbia has ever had?
The highest temperature ever recorded in BC was 44.4C in Lillooet and Lytton simultaneously on July 16th, 1941. Today, in Pemberton, our thermometer recorded 43C in the shade. The end is near.
Why is lab thermometer can't be used as clinical and vice - varsa?
A clinical thermometer typically shows a maximum reading while a lab thermometer typically shows the temperature right now. When you take a thermometer out of a patients mouth (or other place that you are measuring the temperature) you most often want the maximum temperature to keep showing until you reset the instrument. When using a lab oratory thermometer you want the instrument to react as quickly as possible so that changes (up and down) can be noticed and recorded.
What was the hottest day ever in Tampa FL?
The coldest recorded temperature was -2° F on 13 February 1899 in Tallahassee.
When was the earliest recorded temperature?
Various authors have credited the invention of the thermometer to Abū Alī ibn Sīnā (usually known as Avicenna), Cornelius Drebbel, Robert Fludd, Galileo Galilei or Santorio Santorio. But the thermometer was not a single invention, it was a development. The 11th Century was the first official temperature recording.
What is the warmest temperature that has been recorded in space?
If you're talking about actual space, as in vacuum, the only temperature is about -273.5 degrees Celsius, as no atoms move in space. On planets and stars, temperature can vary dramatically, from the temperature of vacuum to the core of the hottest star (could be 40 million Celsius).
Why is thermometer usually shakes before using?
It isn't necessary with new electronic thermometers, but if you still have an old hold-under-your-tongue-for-three-minutes mercury thermometer, the mercury will remain at the last recorded temperature until it is shaken back into the reservoir.
Is the daily temperature recorded in direct sunlight?
No, temperature is normally recorded in the shade.
Where NOT WHAT was the coldest temperature on earth recorded?
The coldest temperature on Earth was recorded in Antarctica.
