Question

Various intense of transformation of energy you see around you

Answer 1

Thermal energy of the exhaust gases converted into thermal energy of steam through the heat exchanger.Thermal energy of steam converted to mechanical energy in the turbine.Mechanical energy of the turbine converted to electrical energy by the generator, which is the ultimate output

In such a system, the first and fourth step are highly efficient, but the second and third steps are less efficient. The most efficient gas-fired electrical power stations can achieve 50% conversion efficiency. Oil- and coal-fired stations achieve less.

In a conventional automobile, these energy transformations are involved:

Chemical energy in the fuel converted to kinetic energy of expanding gas via combustionKinetic energy of expanding gas converted to linear piston movementLinear piston movement converted to rotary crankshaft movementRotary crankshaft movement passed into transmission assemblyRotary movement passed out of transmission assemblyRotary movement passed through differentialRotary movement passed out of differential to drive wheelsRotary movement of drive wheels converted to linear motion of the vehicle
