A battery is used to power an electric heater:

Complete the following paragraph by picking the correct words from those given in the box below:

chemical, gravitational potential, electrical, thermal

When the battery and heater are connected in an electrical circuit, energy is transferred from the chemical energy store of the battery to the thermal energy store of the heater. The electric heater transfers energy from its thermal energy store to the thermal energy store of the surroundings. How is energy transferred between these two energy stores?

When a battery and an electric heater are connected in a thermoelectrical circuit, energy is transferred from the battery's energy store. The electric heater then transfers energy from its thermal energy store to the surroundings. Energy is transferred between these two stores through the conversion of energy forms - from chemical potential energy in the battery to thermal energy in the heater and surroundings.
