Meyer's Relation

Deriving Meyer’s Relation ( Cp = Cv + R )

At Constant Volume dQ = dU + dW , dQ= 1 x Cv x dT dW=0	By I Law of Thermodynamics  By Specific Heat Capacitance  By Work Done	At Constant Pressure dQ' = dU + dW      dQ' =  1 x Cp x dT dW=PdV=RdT
dQ=    dU= Cv dT		dQ' = Cp dT

Look Before You Leap:

Heat in terms of

1) First Law of Thermodynamics,  dQ = dU + dW

(Heat supplied converted to work and internal energy)

2) Molar Specific Heat Capacitance (C_p , C_v)  

dQ= m x C x dT

(Hint to derive Relate the Specific Heat capacitance with the first law of thermodynamics with Cp and Cv)
