This lesson covers the basics of temperature; what it is, how it is transferred, and how it is measured.
Temperature is a physical property of matter.
Specifically, it is the thermal energy contained within the matter.
When an object is heated, it means that thermal energy has been added. This makes the molecules of the object vibrate more.
And when thermal energy is removed, the object cools, and the molecules vibrate less.
This is a property we can take advantage of later when trying to measure temperature.
Increasing the thermal energy of an object also increases the chance that electrons will gain enough energy to jump to the conduction band of their atom.
Having enough energy to be in the conduction band allows electrons to flow freely from one atom to the next, creating an electric current.
This also has uses!
