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?

Measure how hot or cold something is?
temperature! A good thermometer, a thermocouple, a thermoresistance, a pyrometer, etc.
What kitchen utensil is used for measuring temperature?
you use a thermocouple instrument

Can a mercury thermometer be used to measure temperature between 500 and 600?
No, you need another type of device as a thermocouple.
What are the types of thermometer?
Celsius, Fahrenheit, and Kelvin.
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 used to measure temperature?
Temperature is usually measured via expansion/contraction of a liquid (liquid thermometer), differences in expansion/contraction of two metals (bi-metallic strip thermometer), changes in electrical resistance (thermistor or thermocouple) or radiant energy (for example: a pyrometer)
