IT measures it by the alcohol or Mercury being touch by heat so the fluid rises.There is a chemical in the thermometer (the red liquid ) and it reacts to heat or coldness. cold makes it retract and the heat makes it expand

That is NOT a deformation thermometer but an expansion thermometer. A deformation thermometer has a bimetallic strip. This is a strip made by joining together two strips of metal with very different coefficients of thermal expansion. When heated, one of the metals expands much more than the other. But, because they are bonded together it is not permitted to expand freely and as a result the bimetallic strip is deformed. The amount of deformation is converted to a temperature scale for display.

Explain why a thermometer thick walls on its stem?

Thick walls on the stem of a thermometer provide insulation and reduce heat transfer from the environment, resulting in more accurate temperature readings. This helps to prevent external factors, such as air temperature fluctuations, from affecting the measurement inside the thermometer.


Explain why it is important to calibrate a thermometer?

Calibrating a thermometer ensures its accuracy and reliability. It ensures that temperature readings are precise, which is crucial for industries like food, pharmaceuticals, and scientific research where small temperature variations can have significant effects. Regular calibration also helps identify any drift or errors in the thermometer's readings.


Explain the used of a maximum minimum thermometer is used?

A maximum minimum thermometer is used to measure the highest and lowest temperatures reached during a specific period. It contains two separate indicators that show the highest temperature reached (maximum) as well as the lowest temperature (minimum). This type of thermometer is useful for tracking temperature variations over time.


Explain how the common thermometer works by expansion?

A common thermometer works by using a liquid like mercury or colored alcohol that expands when heated and contracts when cooled. This expansion and contraction is used to measure temperature changes and is visualized through a scale on the thermometer, which gives a reading based on the level of liquid inside.


Explain why it is necessary to have a standard thermometer?

Having a standard thermometer is important for ensuring accuracy and consistency in temperature measurements. Standard thermometers are calibrated to a known reference point, which helps in maintaining consistent measurements across different instruments and settings. This is essential for reliable data comparison, quality control, and scientific research.

Explain how a barometer and a thermometer are alike?

A thermometer and a barometer are alike, because a thermometer tells temperature, and a barometer tells air pressure. They sort off connect, because when you have lower air pressure, you get colder temperatures and when you have higher air pressure, you know then that the temperature will be hotter. You can kinda tell by looking at only one piece of data, what the other piece might be. I'm pretty sure that's right, I'm only in 7th grade.

Explain how an ordinary glass fever thermometer is designed?

An ordinary glass fever thermometer is typically made of a sealed glass tube filled with mercury or dyed alcohol. It has a calibrated scale along the length of the tube to measure temperature. When the thermometer is placed in contact with a warm object, the temperature causes the liquid inside to expand and rise up the scale, indicating the temperature value.

Explain how a liquid thermometer measures temperature?

OK basically depending on what thermometer. the glass tube is filled with either alcohol or Mercury. and when it gets hotter, the liquid expands and takes up more space inside the tube. and colder.......the liquid compacts and moves down the tube.....and it's taken years to calabrate the markings on the tube to show the correct reading.
