B It uses only a small fraction of its energy input. C It wastes no energy. D It wastes only a small fraction of its energy input. 0654/13/O/N/12 Q30 Electricity is generated in power stations. Many power stations use high pressure steam to drive the turbines. Some power stations do not use high pressure steam. Which type of power station does not use high pressure steam? A chemical energy (fuel) power stations B geothermal energy power stations C hydroelectric energy power stations D nuclear energy power stations 0654/12/M/J/13 Q30 From which type of energy is electrical energy obtained in a hydroelectric power station? A chemical energy B gravitational energy C nuclear energy D strain energy 0654/13/M/J/13 Q32 An aeroplane flies at a constant speed and height for several hours. Which type of energy must change during this part of the flight? A the gravitational energy of the aeroplane B the kinetic energy of the aeroplane C the store of chemical energy in the fuel tank of the aeroplane D the thermal energy of the aeroplane 0654/11/O/N/13 Q30 A student writes an answer.
