When we use electricity to charge our mobile phones, we convert electrical energy to (a) energy
(WB Pg 109 Q2) Which of the following is a non-renewable way of producing electricity?
natural gas
wind
solar
biomass
Solar (a) help to convert solar energy from the Sun to electrical energy.
Power stations use fossil fuels to produce electricity. First, the furnace will burn the fossil fuels. This converts chemical potential energy (in the fuels) to (a) energy.
Power stations use fossil fuels to produce electricity. First, the furnace will burn the fossil fuels. This converts chemical potential energy (in the fuels) to heat energy.
Second, the heat is used to boil water and turn it into steam. This converts the heat energy to (a) energy of steam.
Power stations use fossil fuels to produce electricity. First, the furnace will burn the fossil fuels. This converts chemical potential energy (in the fuels) to heat energy.
Second, the heat is used to boil water and turn it into steam. This converts the heat energy to kinetic energy of steam.
The steam turns a steam (a) , converting the kinetic energy of steam into kinetic energy of turbine.

Second, the heat is used to boil water and turn it into steam. This converts the heat energy to kinetic energy of steam.
The steam turns a steam turbine, converting the kinetic energy of steam into kinetic energy of turbine.
Lastly, the turbine turns a (a) , converting kinetic energy of turbin into electrical energy. Electricity is then distributed to our homes!
