Answer :
Final answer:
In a battery, chemical energy is converted into electrical energy, while in a solar cell, solar energy is transformed into electric energy.
Explanation:
Energy change in a Battery: In a battery, chemical energy is converted into electrical energy. This process involves the transfer of electrons between the anode and the cathode, leading to the creation of an electric current that can power devices.
Energy change in a Solar Cell: In a solar cell, solar energy is transformed into electric energy. When sunlight hits the solar cell, it creates an electric current due to the photovoltaic effect.
Therefore, the energy change in a battery involves converting chemical energy into electrical energy, while in a solar cell, solar energy is transformed into electric energy.
