- apply the law of conservation of energy to analyse system efficiency in terms of energy inputs, outputs, transfers and transformations
- Example: explaining that the law of conservation of energy explains that total energy is maintained in energy transfer and transformation in a system
- Common trap: explaining efficiency and recognising that in energy transfer and transformation a variety of processes can occur, so that the amount of usable energy is reduced and the…
