Relier Pairs Central Heating ModelVersion en ligne The central heating model helps to explain what happens in an electric circuit. Match up the statements for the model to what goes on in the circuit. par Gideon Williams 1 Water flows through the pipes 2 All the water stays in the pipes 3 Pipes let water flow through them 4 The water has most energy when it has just left the boiler, and least energy when it returns to the boiler 5 The boiler transfers heat energy to the water 6 Adding more radiators will make it harder for water to flow around the circuit 7 The pump pushes the water through the pipes 8 If you measured the amount of water flowing, you would get the same answer everywhere in the central heating system 9 In the radiator, energy is transferred from the hot water to the room by heating Charges flow through the wires Wires let charges flow through them The cell pushes the charges around the circuit Adding more bulbs will make it more difficult for the charges to flow around the circuit The charges have the most energy when they have just left the cell, and the least energy when they return to the cell In the bulb, electrical energy is transferred to the surroundings by light and heating If you measured the current flowing, you would get the same reading everywhere in the circuit All the charges stay in the wires The cell transfers energy to the charges
