Thermocouple is made up with the junction of two different metals(e.g. antimony and bismuth). This is the device used to measure the temperature due to the fact that when two junctions are placed at different temperature a potential difference developed (thus electrical signal) which is proportional to the difference in the temperature of the two junction. This is very sensitive device.

Describe how a liquid thermometer and a thermocouple are the same and how they are different?
Both are used to measure temperature, but by different means. A liquid based thermometer uses the expansion of a liquid with temperature to indicate the temperature, while a thermocouple uses electrical differentials at the junctions of dissimilar metals to do so. So in the case of the liquid thermometer the reading is position of a liquid in a tube, and in the case of a thermocouple it is a voltage measured with a voltmeter. Thermocouples may be better suited to measuring extreme temperatures.
What year was the thermometer invented?
the thermometer was invented in 1708 .
What are you measuring with a common thermometer?
temperature
What did Hans Schwarzkopf invent?
thermometer
Which Swedish scientist discovered thermometer?
celsius
What words start with the prefix therm?
thermometer, thermocouple, thermodynamics
What kitchen utensil is used for measuring temperature?
you use a thermocouple instrument

What might be the advantages and disadvantages of using a thermocouple instead of regular lab thermometer?
Advantages of using a thermocouple instead of a regular lab thermometer include faster response time, wider temperature range, and higher accuracy. Disadvantages may include higher cost, the need for calibration, and susceptibility to electromagnetic interference.
What are the types of thermometer?
Celsius, Fahrenheit, and Kelvin.
Which thermometer is used to measure the temperature of burning match sick?
A thermocouple thermometer is typically used to measure the temperature of a burning matchstick. This type of thermometer can withstand high temperatures and provide accurate readings in extreme heat conditions.
Why would a thermocouple be used instead of a thermometer?
A thermocouple is used instead of a thermometer when the temperature measurement needs to be taken in harsh or high-temperature environments, as thermocouples are more rugged and can withstand extreme conditions. Thermocouples also provide faster response times and can measure a wide range of temperatures compared to traditional thermometers.
Function of cork borer?
Very simple answer: to make a hole in a cork or plastic stopper; the scope is to insert a tube, thermocouple, thermometer, etc.
What is the advantages and desvantadges of sing a thermorcouple instead of a regular lab thermometer?
A thermocouple may be more useful than a regular lab thermometer if you want to measure fairly high temperatures. A disadvantage is that thermocouples may be subject to wear and may not be very accurate or precise. The thermocouple must be calibrated against a known standard before it is used for measurement.
What is the difference between a thermometer and a thermocouple?
A thermometer measures temperature using a temperature-dependent physical property, such as liquid expansion or electrical resistance. A thermocouple, on the other hand, generates a voltage proportional to the temperature difference between its two junctions, based on the Seebeck effect. Thermocouples are typically used in more extreme temperature environments compared to thermometers.
What instrument measures how hot or cold something is?
A thermometer is the instrument used to measure how hot or cold something is. It typically consists of a small tube filled with a liquid (such as mercury or alcohol) that expands or contracts based on the temperature, indicating a numerical value on a scale.
