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.

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 changes in the atmosphere?
There are many types of instrument used to measure air pollution. Different types include:Absorption plates trap pollutants such as sulfur dioxide on a reactive plate for a measure of air contaminantsAn a high volume air sampler is used to measure pollution levels in the atmosphere by collecting solids on a filter paperLasers measure contaminants by the amount of light reflected or removed by specific chemical contaminants in the air between the emitter and receiverField gas chromatography passes air through a packed column to measure types of gaseous contaminantAir samples can be taken an stored in Teflon bags for later laboratory analysisScrubbers can collect contaminants from an air sample in the field for later analysisPhytotoxicolgic chambers can pass air over plants to determine the impact on plant growthOpacity meters measure haze
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
How is temperature taken through an axillary placement?
In axillary placement, the silver tip of the thermometer is placed under the patient's right armpit, with the patient's arm pressing the instrument against the chest. The thermometer should stay in place for six to seven minutes.
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 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 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 measure how hot or cold something is?
The simplest method is to use a thermometer.
What a thermometer ued for?
A thermometer is used to measure the temperature of an object or a person. It can help determine if someone has a fever or monitor the temperature in various settings such as in cooking, scientific experiments, and weather forecasting.
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!
How do you replace instrument panel lights?
you take apart the dash and get to the instrument panel. then you take the instrument panel out and on the back of the panel you'll will see the lights
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.
How to measure thickness accurately and effectively?
To measure thickness accurately and effectively, use a caliper or micrometer to take precise measurements. Ensure the measuring instrument is properly calibrated and use it consistently across the material being measured. Take multiple measurements and calculate the average for increased accuracy.
