Rewriting the question

is it entropy?

Manish Shankar ·

absolute temperature means temperature in Kelvin(absolute scale)

so we have to plot (Cp/T) vs T

Manish Shankar ·

now it can be solved
and the answer is entropy

Manish Shankar ·

Cp/T=(dH/dT)/T=(dH/T)/dT=dS/dT

so the graph is dS/dT vs T

area=∫(dS/dT)dT=S(T)-S(0)

S(0)=0

area = S(T) absolute entropy at any temperature T

Sir i got the answer.........answer is enthalpy.....

you made a small mistake in the beginning....Cp=dQ/dT.......not dH/dT...

anyways thanks for help....

δQ=dH at constant pressure
so dH=CpdT

and i think answer should be entropy

you should again check the answer
