What kitchen utensil is used for measuring temperature?

you use a thermocouple instrument


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 apparatus used to measure temperature?

We can use thermometers, thermocouples, thermoresistances, pyrometers etc.


Can a mercury thermometer be used to measure temperature between 500 and 600?

No, you need another type of device as a thermocouple.


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 types of equipment would be used to measure the boiling point of a liquid?

You need two tools. To measure the air pressure you use a barometer and to measure the temperature at which the substance boils you use a thermometer. The boiling point is defined as the temperature at which the vapor pressure equals atmospheric pressure.


Is thermocouple used in fridges?

Yes, thermocouple is used in fridges !


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)


What is the purpose of a temperature gauge?

To measure temperature. A gauge can be used instead of a thermometer, and is generally used in industry where a thermometer might be too fragile


Which two measuring instruments can give the same reading in the Stevenson screen?

The two measuring instruments that can give the same reading in the Stevenson Screen are a thermometer and a thermocouple. A thermometer measures the temperature of the air inside the Stevenson Screen, and a thermocouple measures the temperature of the air outside the Stevenson Screen. Both instruments measure the same temperature, allowing for accurate readings to be taken. The Stevenson Screen is a ventilated, white-painted metal box with louvers that is used to house meteorological instruments. It is used to protect the instruments from direct sunlight and other external influences, allowing for more accurate measurements. The thermometer inside the Stevenson Screen measures the temperature of the air inside the box, while the thermocouple measures the temperature of the air outside the box. Both instruments are designed to measure the same temperature, allowing for the same reading to be taken from both instruments. The Stevenson Screen is typically used to measure the temperature, humidity, and wind speed of the surrounding environment. It is also used to measure the air temperature, dew point, and wind chill. The thermometer and thermocouple inside the Stevenson Screen can give accurate readings for all of these measurements. In order for the thermometer and thermocouple to give the same reading in the Stevenson Screen, they must be calibrated regularly. Calibration ensures that the instruments are measuring the same temperature and that their readings are accurate. It is important to regularly check the calibration of the instruments to ensure that the readings they are providing are accurate. In addition to the thermometer and thermocouple, the Stevenson Screen can also house other instruments such as barometers, hygrometers, and rain gauges. As with the thermometer and thermocouple, all of these instruments must be calibrated regularly to ensure accurate readings. In conclusion, the two instruments that can give the same reading in the Stevenson Screen are the thermometer and the thermocouple. Both instruments measure the same temperature and must be calibrated regularly to ensure accurate readings. By doing this, the Stevenson Screen can be used to accurately measure the temperature, humidity, and wind speed of the surrounding environment, as well as other meteorological measurements.
