Heat transfer and efficiency

• Appliances transfer energy but not all the energy is transferred in useful ways
• Main types of energy: Most Kids Hate Learning GCSE Energy Names
• Magnetic
• Kinetic
• Heat
• Light
• Gravitational potential
• Chemical
• Sound
• Electrical
• Elastic potential
• Nuclear

• Different types of energy can be transferred from one type to another
• Energy transfer diagrams show each type of energy, whether it's stored or not, and the processes taking place as the energy is transferred

• Sankey diagrams…
