, ENERGY CONVERSION
The diagram shows how different forms of energy can be converted to
another form of energy
, Thermodynamics is the study of how energy gets converted
from one form to another.
Details on how the laws of thermodynamics apply to the
conversion of energy are given below.
The first law of thermodynamics states that:
Energy can neither be created nor destroyed, it can only be
transformed from one form to another.
This is also known as the law of conservation of energy or the law of
energy conversion.
There are various types and forms of energy. Some examples of
everyday energy conversions are provided below.
