Matter generally expands as it warms, and contracts as it cools. In liquid thermometers, as the liquid heats and expands, it is directed up a tube with markings to show the exact amount of expansion. In Bi-metal thermometers, there is a strip of two different metals pressed together. These metals expand and contract at different rates. As a result, the strip will coil and uncoil with the rise and fall of the temperature. A needle attached to this coil can show the temperature.
The thermometer scales the temperature.

A USB thermometer works in much the same way any digital thermometer works by measuring the temperature of the individual via contact with their skin or mouth. The USB thermometer is then able to be plugged into a computer via the USB to record and chart the findings.

Sensitivity of a thermometer is calculated by dividing the change in temperature measured by the thermometer by the change in the actual temperature. This gives a measure of how accurately the thermometer can detect small changes in temperature.
The property measured by a thermometer is temperature. Thermometers can detect and display temperature readings in various units such as Celsius or Fahrenheit.
A thermometer detects temperature by measuring the amount of heat energy present in a substance or environment.
In a thermometer, a variable is the temperature being measured. Thermometers detect changes in temperature by expanding or contracting a substance, such as mercury or alcohol, which then indicates the temperature on a scale.
The resolution of a thermometer refers to the smallest interval or increment between temperature readings that the thermometer is capable of measuring. It indicates the level of detail or precision with which temperature can be recorded. A higher resolution thermometer will be able to detect smaller changes in temperature compared to a lower resolution thermometer.
Low sensitivity of a thermometer means that the thermometer is not able to detect small changes in temperature accurately. This can result in less precise temperature readings and a reduced ability to differentiate between slight temperature variations.
When a thermometer displays "L", it typically indicates that the temperature reading is below the thermometer's lower limit or range of measurement. This could be due to the temperature being too low for the thermometer to accurately detect.
The resolution of a digital thermometer is the smallest incremental change in temperature that the thermometer can detect and display. It is typically expressed in degrees Fahrenheit or Celsius. For example, a thermometer with a resolution of 0.1°C can display temperature changes as small as one-tenth of a degree.
Increasing the sensitivity of a thermometer allows it to detect smaller temperature changes more accurately. This can be useful in applications where precise temperature measurements are needed, such as in scientific research or industrial processes.
An infrared thermometer is another device that can measure temperature without direct contact. It uses infrared technology to detect thermal radiation emitted by an object and convert it into temperature readings.
The substance in a digital thermometer that tells us the temperature is usually a thermistor. A thermistor is a type of resistor whose resistance changes with temperature, allowing the thermometer to detect the heat variations and provide an accurate temperature reading.
