Ch 13.4 - PPT - Conservation of Energy
... – Whenever the total energy in a system increases, it must be due to energy that enters the system from an external source. • Thermodynamics describes energy conservation. – For any system, the net change in energy equals the energy transferred as work and as heat. – This form of the law of energy c ...
