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.

Explain how a deformation thermometer measures temperature?

A deformation thermometer measures temperature by the mercury or alcohol in the thermometer being touched by heat. The cold makes the liquid in the thermometer retract, and heat makes it rise or expand.


Ho does a thermometer measure temperature?

A thermometer measures temperature by using the liquid inside of the thermometer. It measures temperature by Celsius and Fahrenheit.


What is the difference between a liquid and an air thermometer?

How are an air thermometer and a liquid thermometer different?

A liquid thermometer measures lowest temperature while air thermometer measures lowest temperature of the day!! Hope this helps


What measures the temperature of the liquid?

A thermometer will measure the temperature of a liquid.


Explain how a thermometer works?

The thermometer works by measuring the temperature of the air or liquid around it. The substance being tested will heat or cool down the liquid in the thermometer to the temperature that it is.


What is the the name of the object a thin glass tubbed filled with liquid that measures temperature?

How is a liquid thermometer and an air thermometer different?

They are both have diffrnet skills like one measures air and one measures liquid


What does the thermometer actually measure?

A liquid thermometer actually measures the thermal expansion of the liquid (mercury).


What should you use to measure the temperature of liquid?

A liquid in glass thermometer should be used to measure the temperature of a liquid.


How is a thermometer used?

A thermometer is used to measure air temperature, or the temperature within a solid or liquid.


Why is thermometer dipped in liquid before use?

to get the thermometer at room temperature.


Why does the liquid in a thermometer rise when the temperature increases?

The liquid expands as its temperature increases. This is the same as saying that it occupies more space as temperature increases. Therefore it 'uses up' more of the space inside the thermometer as the temperature increases.


Is Hg is a solid at room temperature?

Hg is liquid at room temperature. If you take a look to a thermometer; there is mercury in the thermometer and it's liquid that's why it can go up.


Whats the difference of fever thermometer and laboratory thermometer?

fever thermometer is used by the doctors and they are adjusted to body temperature whereas lab thermometer is adjusted to liquid temperature


How do you measure the temperature of a liquid correctly?

You put a thermometer in it, for at least a minute, and then read the thermometer with the bulb still in the liquid.


What features do a liquid thermometer and lab thermometer have in common?

What happen to the liquid in a thermometer when it gets warm?

The liquid expand from heat. We use these expansion to indicate temperature. Common thermometer liquid is Mercury and alcohol.


In a thermometer an indication the temperature is dropping is?

In a liquid thermometer the liquid will retreat towards the reservoir bulb at the end of the thermometer. In other types of thermometers - digital, dial, etc. - decreasing values of the reading are an indication that temperature is dropping.


Why does alcohol in a thermometer drops when the thermometer is placed in a cold liquid?

The contraction of a material depends on the temperature; the volume of alcohol decrease at low temperature.


How can you measure temperature?

A way you can measure temperature is using a liquid thermometer.


Why the level of mercury should change at all when the bulb of the thermometer is brought in contact with another object?

a liquid changes its volume relative to its temperature


Why does liquid inside a thermometer rise as the temperature s increase?

Most materials expand with the temperature increases. In this case, the liquid in the thermometer expands faster than the glass that holds it.


What does the thermometer do in the furnace control system?

A thermometer does nothing in a furnace control system other than indicate temperature at a thermostat. A physical thermostat on the other hand controls variances of temperature (called anticipation) using the principles of a thermometer which is expansion of a liquid in a sealed capillary/bulb. A thermistor is another device used in electronic temperature measurement at nominal to extreme temperatures. It measures the resistance of power to indicate temperature.
