Imagine in a balloon with perfectly stretchy walls
as you add Q, the gas expands keeping the pressure constant
That means that work is done pressure * area times expansion distance or integral of p dV. Meanwhile the gas heats up.
Look up constant pressure expansion.
W = n R delta T
Q = n Cp delta T
Q/W = n Cp delta T/n R delta T
= Cp/R
BUT for an ideal monatomic gas
Cp = 5R/2
so here
Q/W = 5/2
Heat Q is added to a monatomic ideal gas at constant pressure. As a result, the gas does work W. Find the ratio Q/W.
What in the world is this asking??

OMG. That was correct. Thank you. I'll never know how you people do this.
