Joule,s Law

It state "The change of internal energy of a perfect gas is directly proportional to the change of tempreture."
 Mathematically
                             dE = mcdT = mc(T2 - T1)
                            
  where
                                m = Mass of the gas
                                c = A constant of proportional, known as speciefic heat.
