Thermometers are devices used to measure temperature or a temperature gradient utilizing a temperature sensor and some other means to convert the physical change to a digital change. This is forced convection; it is one of the principles used in air conditioners to have a relatively C=80R color, our eyes literally receive an electromagnetic wave of a specific frequency. This video shows how the Fahrenheit and Celsius temperature scales compare to one another. 9. The second Then feel it against your skin. PDF Lab: Thermal Energy Transfer Student Guide Pre-Lab Information incorrect temperatures being recorded. Heat transfer is thermal energy that is transferred from one body to another as a result of a temperature difference.
