here are the energy flow diagrams for the appliances: ACTIVITY 7: Draw a flow diagram to show the input and output of energy. 2. Use a flow diagram to show the input and output of energy for each appliance. Kettle: Input Energy: Electrical energy Appliance: Kettle Output Energy: Heat energy (to water) Flow Diagram: Electrical energy → Kettle → Heat energy Wind-up radio: Input Energy: Movement energy (from winding) Appliance: Wind-up radio Output Energy: Sound energy Flow Diagram: Movement energy → Wind-up radio → Sound energy Iron: Input Energy: Electrical energy Appliance: Iron Output Energy: Heat energy (to clothes) Flow Diagram: Electrical energy → Iron → Heat energy Fan: Input Energy: Electrical energy Appliance: Fan Output Energy: Kinetic energy (of air) Flow Diagram: Electrical energy → Fan → Kinetic energy Solar lighting system: Input Energy: Light energy (from Sun) Appliance: Solar lighting system Output Energy: Light energy (at night) Flow Diagram: Light energy → Solar lighting system → Light energy Torch: Input Energy: Chemical energy (from battery) Appliance: Torch Output Energy: Light energy Flow Diagram: Chemical energy → Torch → Light energy 3. Do some research to find out about another appliance that uses energy directly from the Sun. Solar Calculator: Input Energy: Light energy (from Sun) Appliance: Solar Calculator Output Energy: Electrical energy (to power calculator) + Light energy (for display) Flow Diagram: Light energy → Solar Calculator → Electrical energy + Light energy What's next? 📸
