2. How do we measure Water Temperature?

Temperature is measured as degrees on a standard scale, such as Fahrenheit or Celsius.

Water temperature is often measured with a thermometer. A thermometer has a liquid inside that expands as the temperature increases. The temperature is read from the scale printed on the thermometer.

Temperature is also commonly measured with an electronic device called a thermistor (thermal resistor). A thermistor measures temperature by measuring the resistance to electric flow in a metal. The electrical resistance of a metal will increase as the temperature increases.
