Whenever there are energy transfers in a system only part of the energy is usefully transferred. The rest of the energy is dissipated so that it is stored in less useful ways. This energy is often described as being 'wasted'. Describe with examples where there are energy transfers in a system, where there is no net change to the total energy of a closed system (qualitative only). Describe, with examples, how in all system changes, energy is dissipated so 1 Ask students to explore questions such as: Can energy be created or destroyed? What happens to energy that is lost? How can we reduce the amount of energy being wasted by a machine? What is the best way to reduce heat loss in the home? Video clips - YouTube: Teachit Science resource Teachit Science resource
