What was the first liquid used in a thermometer?
The first thermometer was a tube filled with water and air.
Is the external bulb of a thermometer also made of mercury?
The red liquid in a thermometer is Mercury, which is usually encased in a glass tube
How does an air thermometer work?
An air thermometer has a bubble of liquid inside the tube and when the air inside of the tube heats up or cools down, the air takes up either more or less space inside of the tube, causing the bubble of liquid to either move upwards or downwards, indicating the temperature.
What thermometer is based on the metric system?
That depends on what units the thermometer is calibrated in. The SI unit for temperature is the kelvin, but degrees Celsius commonly used, if the thermometer reads in kelvin or degrees Celsius then it is a metric tool.
What is in a thermometer besides Mercury?
There is nothing else in a mercury thermometer. However, some similar (glass tube-type) thermometers contain alcohol instead of mercury. Ray
What was the first liquid used in a thermometer?
The first thermometer was a tube filled with water and air.
Who invented the first test tube?
John Flamsteed invented the first test tube.
How did Galileo invent the thermometer?
He did not actually invent the thermometer, which would have shown a scale of temperatures. He invented the "thermoscope" -- a device that showed increase or decrease of temperature using the expansion of a liquid in a tube.
Who first invented the cathode ray tube?
The cathode ray tube was invented in 1897 by Ferdinand Braun.
Function of bent tube earth thermometer?
The bent tube Earth thermometer is a kind of a measurement that is used for measuring temperature of the earths crust.
What is the signal conditioner of mercury-in-glass thermometer?
The capillary tube of the thermometer ( in case of a mecury thermometer).
Who element used of the glass tube of clinical thermometer to measure thermometer?
mercury
Who invented the Mercury thermameter?
A mercury-in-glass thermometer, invented by German physicist Daniel Gabriel Fahrenheit, is a thermometer consisting of mercury in a glass tube. Calibrated marks on the tube allow the temperature to be read by the length of the mercury within the tube, which varies according to the heat given to it. To increase the sensitivity, there is usually a bulb of mercury at the end of the thermometer which contains most of the mercury; expansion and contraction of this volume of mercury is then amplified in the much narrower bore of the tube. The space above the mercury may be filled with nitrogen or it may be less than atmospheric pressure, which is normally known as a vacuum.
What is a capillary tube in instrumentation terms?
a thermometer--
Why is the thermometer placed in a tube separate from the culture?
If the thermometer was in a culture tube it would interfere with the subsequent transfers of culture to plates across the time intervals.
How does a thermomerator measure temperature?
that depends on what type of thermometer. The tube thermometer, the kind with a glass tube with a red liquid in it, uses a small amount of mercury in a very small tube. When the mercury is heated, it expands, pushing further up the tube, as it cools it contracts, going down the tube. A dial thermometer also works on expansion and contraction, but with a coil instead of mercury.
What is a thermometer bore?
A bore refers to the extremely fine or narrow tube found in a thermometer. It is called a narrow bore or a capillary.
