A redox reaction be used as a source of electrical energy only when two half-reactions are physically separated. <span>The electrons that are released at the anode flow through the wire, producing an electric current. Galvanic cells therefore transform chemical energy into electrical energy that can then be used to do work.</span>

Explanation:

Electrical energy is the energy produced due to flow of electrons.

Whereas a reaction in which oxidation and reduction reaction takes place is known as a redox reaction. Basically, there is exchange of electrons that take place in a redox reaction.

For example, H_{2} + F_{2} \rightarrow 2HF

Oxidation half reaction: H_{2} \rightarrow 2H^{+} + 2e^{-}

Reduction half reaction: F_{2} + 2e^{-} \rightarrow 2F^{-}

Hence, this flow of electrons acts as a source of electrical energy.

The enthalpy energy in condensation process is negative because it releases energy
The entropy in  will also decreases .
Temperature affected this change because it will now create free energy if added with this result this is the condestion process
