The energy released (sometimes called enthalpy) is calculated using the following equation: \({E_h} = cm\Delta T\) \({E_h}\) is the heat energy released (in kJ or kJ mol-1) \(c\) is the specific ...

The motor turns. Charges flow through the filament bulb. Energy is transferred by electrical working to the thermal energy store of the filament bulb. The bulb gets hot. Energy transfers from the ...
