How does the instrument used to measure air temperature differ from the instrument used to take your temperature?

Those thermometers use liquid crystals to measure temperature. More specifically, they use chiral nematic liquid crystals--long asymmetric molecules that arrange themselves in orderly spirals in the liquid. When light strikes these spiral structures, some of it reflects. But the reflection is strongest when the light's wavelength is an integer or half integer multiple of the spiral's pitch--the distance between adjacent turns of the spiral. Since light's wavelength is related to its color, the light reflected by these liquid crystals is colored. Because the pitch of a chiral nematic liquid crystal changes with temperature, so does its color. Slightly different liquid crystals are inserted behind each number on the thermometer so that each number becomes colored at a different temperature.

∙ 15y agoThey really necessarily are not the same because air is a gas and obviously liquid is a liquid, and they have to be measured differently because you can tel a big difference in the two types of matter.

∙ 16y agoliquid thermometer measures the lowest temperature while air thermometer measures the lowest temperature of the day. liquid uses liquid and air uses air.
Wiki User
∙ 11y agoA liquid thermometer measures lowest temperature while air thermometer measures lowest temperature of the day!!
Hope this helps
Wiki User
∙ 16y agoeven this may not be right but it was worth a try.!!!!!

∙ 12y agoThey are both have diffrnet skills like one measures air and one measures liquid

What is used to measure heat in the air?
The best is a thermometer, another way to get the temperature outside is to pour water in a bowl, leave it out there for a couple of minutes and then take a thermometer and put it in the water.
What is the temperature of vinegar in celsius?
As with any other substance, without any outside influence, it will take on the ambient temperature.
What instrument measures precipitation by bouncing radio waves off rain or snow?
Mostly, just a ruler and a white snow board for the snow to fall on in an unobstructed area. There are automated methods, such as snow pillows that sense the weight of the snow, and even ultrasound, but a ruler is still the most reliable method when humans are available to do it.Usually it's a ruler
Why ice does not melt at 5 degree?
I am going to assume your talking about Fahrenheit. Which would take 32 degrees Fahrenheit for ice to begin to melt (albeit slowly). If you come from a place that uses Celsius its understandable to be confused by this at it will seem illogical as Celsius is a simpler and a more logical way to measure temperature.
What simple measures can you take to reduce the environmental impact of using a computer?
The simple measure that I can take to reduce the environmental impact of a computer is switching it off when it is not in use.
How does the thermometer used to measure air temperature differ from the thermometer used to take your temperature?
A thermometer used to measure air temperature uses a glass tube filled with a liquid either alcohol or mercury. When the temperature increases the particles of liquid expand, filling the glass tub. Thermometers that are used to measure you body temperature uses infrared sensors.
What is the laboratory instrument used to measure curved lines?
At first they will use the twine to measure the curved lines and then they will take one scale and looke the measure
What is a thermometer used for?
The use of a thermometer is to measure hot and cold in Fahrenheit and in Celsius. To measure body temperature, air temperature, atmosphere temperature. It is a scientific instrument to record temperature. It's used to measure temperature of various things. For examples- the human body , weather, liquids etc The word "thermometer" literally means to "measure heat". As such, variations of the device are used to measure the heat of numerous items, including, but not limited to, the body heat of a human or animal, or to ensure proper cooking temperatures, or to trigger a device, such as via an automobile radiator's thermostat, or even to measure the temperature of distant stars.

How do you take care thermometer?
the thermometer is an object that we going to measure of an temperature of one person.
How do you measure how hot or cold something is?
The simplest method is to use a thermometer.
What is the right way to measure the temperature of MAP or vacuum-packed foods?
The proper way to take the temperature of vacuum packed foods is with a metal stem thermometer. To take the correct temperature, put the thermometer in the center of the food.
Describe an experiment used to find out whether there is any temperature change on mixing ethanol and water?
Measure equal amounts of water and ethanol in separate containers. Take temperature of both. Add ethanol to water and take temperature.
Is temperature measured 20 meters off the ground?
Not necessarily. I I wanted to measure my son's body temperature, I would not take him 20 metres up!
What are the uses of weather thermometer?
to measure the temperature of a person or animals (living things) to see if their temperature is too high than the average temp.
What a thermometer ued for?
As soon as your symptoms have officially cleared up (see doctor)
What is the use of laboratory thermometer?
As well known, thermometer is an instrument used to measure temperature. Thermo is referred to heat and -Meter is referred to the measuring instrument. The laboratory thermometer is normally mercury based as it expands at a steady rate and has a higher density than water's. This allow it take a small height to expand compare to water which is 13.6x more than the height of mercury when it expands as their density are 13600kgm/s for mercury and 1000kgm/s for water. Furthermore, the mercury used is not poisonous and therefore is safe to be used by students at school. Laboratory thermometer is used to measure low temperature which is between -10 degree Celsius to 120 degree Celsius. This is because in school laboratory, the experiments we conduct just within a small range of temperature around the room temperature., which is about 27-29 degree Celsius.
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.
