What are the two scales used to measure temperature and where are they used quizlet?
Terms in this set (8) What are the three systems for measuring temperatures that are widely used? the Celsius scale, the Kelvin scale, and the Fahrenheit scale. The size of the temperature unit (the degree) is the same for the Kelvin and Celsius scales.
What does the 1st law of thermodynamics state?
The first law of thermodynamics states that energy can neither be created nor destroyed, only altered in form. For any system, energy transfer is associated with mass crossing the control boundary, external work, or heat transfer across the boundary.
What is the most accurate method for calibrating?
The ice-point method is the most widely used method to calibrate a thermometer.
Which is the most used thermometer in the world?
Such items can include well known “ Thermometer “, or as more correctly it is called – Mercury Medical Thermometer. Even after the emergence of a large number of models of electronic thermometers, mercury thermometer has not lost its popularity and is the most common device for measuring the temperature of human body.
Which is the correct temperature for a thermometer?
We make sure that it falls below the 37⁰C mark or the 98⁰F mark, the normal human body temperature. The thermometer has then kept under the tongue or under the arms in order to get the reading on the thermometer. The thermometer is then held close to the eye as shown in figure 3 in order to see the correct reading.
What’s the name of the device used to measure temperature?
Temperature is defined as the measure of the degree of hotness or coolness of an object. The device used for measuring temperature is called a thermometer.

Which is an example of a laser thermometer?
They are sometimes called laser thermometers if a laser is used to help aim the thermometer, or non-contact thermometers or temperature guns, to describe the device’s ability to measure temperature from a distance. Examples of use IR thermometers can be used to serve a wide variety of temperature monitoring functions. A few examples include:
How is the temperature of a person measured?
Measuring a person’s temperature can be done in several ways. One method to measure a person’s surface temperature is with the use of non-contact infrared thermometers (NCITs). NCITs may be used to reduce cross-contamination risk and minimize the risk of spreading disease.
