This lesson introduces how electrical devices transform electrical energy to thermal energy to alter the temperature of a substance resulting in the freezing, melting, or boiling of the substance. Each electrical device produces thermal energy as a byproduct that is conducted from a source like an electrical socket or battery; this lesson discusses how that energy is transferred while also comparing and contrasting the states of matter of different substances.
This is lesson 1 in a Unit on Detecting Thermal & Electrical Energy.
