Apes Energy Resources

According to the second law of thermodynamics, whenever one form of energy is transformed into another,

• all of the energy is put to work

• all of the energy is converted into a less usable form, like heat

• some of the energy is converted to a less usable form, like heat

• 50% of the energy is put to work, the rest is lost as heat
