How do I approach the problem if Cp is given as a function of volume?

Here is the problem I'm trying to solve: A system undergoes Isothermal Expansion under the atmosphere. For the system, $ C_p = a + \frac{b}{V} \ $. The process is given by $ P_{ATM}, V_1, T_1 \...

Molar heat capacity of water at equilibrium

Molar heat capacity is defined as the heat energy given to one mole of substance to raise its temperature by 1 degree celcius (or 1 Kelvin) Mathematically, $$C_{m} = \frac {q}{n\Delta T}$$ Here's a ...

Can anyone help me with the derivation for the formula of entropy?

I have this formula in the chapter of thermodynamics: $$\Delta S = n C_v \ln\left(\frac{T_2}{T_1}\right) + n R \ln\left(\frac{V_2}{V_1}\right),$$ where $\Delta S$ is entropy, $n$ moles, $C_v$ molar ...

Are Cp and Cv functions of temperature?

I have read that Cp and Cv are independent of temperature for the case of a perfect gas whereas for an ideal gas it will vary with temperature. The variation in Cp and Cv with temperature is ...
