Answer to Question #4673 in Molecular Physics | Thermodynamics for Lauren

Question

You have one mole of a van der Waals fluid with the initial value of its volume to be 3b and its initial pressure to be 2a/(9b2), where a and b are the van der Waals constants for the fluid along with c = 3/2. How much heat needs to be added at constant pressure to cause the temperature to double? Your answer will be “number” a/b.
Discuss how your answer for this amount of heat added compares with the amount of heat that would have been needed to double the temperature of an ideal gas over the same temperature range
