Specific heat ratio difference between dry air and moist air, which reads

For dry air cp/cv = 1.4, but for moist air it is smaller: cp/cv ~ 1.3. What is the reason for this difference?

A fairly standard homework question that probes if you understand what the difference between heat capacity at constant volume vs pressure means. Seems black and white to me, but lets test the boundary.

To me, the most likely issue for the poster is not unwrapping the ratio of the two to get back to the heat capacities proper.

Vote up if you think this should be on topic under the new policy, or vote down if you think it should be off topic under the new policy.
