Some of the energy was converted to kinetic energy and some to heat.
100% of the chemical potential energy was converted to electrical energy.
None of the battery's energy was given off as heat.
When an organism eats food, energy becomes available for biological activities. In the process, some of the energy enters the environment as heat. According to the Law of Conservation of Energy, _____________.
no energy is lost.
some energy is changed to heat.
the energy which is given off is not part of the system.
the energy which is not immediately used by the organism cannot be stored and is lost.
