The change of one from of energy into another form of energy is known as transformation of energy.
Example:
Transformation at a Hydroelectric Power House
At a hydroelectric power house, the potential energy of water is transformed first into kinetic energy and then into electrical energy.
Energy Transformation at a Thermal Power House
At a thermal power house, chemical energy of coal is changed into heat energy, which is further converted into kinetic energy and electrical energy.
USING ENERGY CONVERTERS
Electric Motor: A motor converts electrical energy into mechanical energy.
Electric Iron: An electric iron converts electrical energy into heat energy.
Electric Bulb: An electric bulb converts electrical energy into heat energy which is further converted to light energy.
Radio: A radio first converts electrical energy into kinetic energy and then into sound energy.
Steam Engine: A steam engine converts heat energy into kinetic energy for mechanical energy.
Car Engine: The car engine converts the chemical energy of petrol into heat energy and then into kinetic energy (or mechanical energy).
(or Mechanical energy)
Cell (or Battery): A cell (or battery) converts chemical energy into electrical energy.
Solar Water Heater: A solar water heater converts light energy to heat energy.
