Study Notes
What is a Thermometer?
- A device that measures temperature or temperature gradient (degree of hotness or coldness of an object)
Components of a Thermometer
- Temperature sensor (e.g. bulb of mercury-in-glass thermometer or pyrometric sensor in infrared thermometer)
- Means of converting temperature change into a numerical value (e.g. visible scale or digital readout)
Applications of Thermometers
- Widely used in technology and industry to monitor processes
- Used in meteorology
- Used in medicine
- Used in scientific research
Temperature Scales
- Individual thermometers can measure degrees of hotness, but readings cannot be compared unless they conform to an agreed scale
- Absolute thermodynamic temperature scale exists
- Internationally agreed temperature scales approximate the absolute thermodynamic temperature scale
