That's probably not what you're looking for, but it is technically correct...

Oops, it's Cp, not C.

I don't remember a numerical value... I remember equations existing, but I don't remember how to do 'em... It's summer.

5/2R for a monatomic gas and 7/2R for a diatomic gas.

A glass bulb of volume 300 cubic centimeters is connected to another of volume 200 cubic centimeters by means of a tube of negligible volume. The bulbs contain dry air and are both at a common temperature and pressure of 20 degrees Celcius and 1.000 atm. The larger bulb is immersed in steam at 100 degrees Celcius and the smaller bulb is immersed in melting ice at 0 degrees Celcius. What is the final common pressure?
