PLEASE ONLY ANSWER QUESTION B
A) A balloon contains 4.90 moles of a monatomic ideal gas. As energy is added to the system by heat (say, by absorption from the Sun), the volume increases by 25% at a constant temperature of 34.0°C.

Find the work Wenv done by the gas in expanding the balloon, the thermal energy Q transferred to the gas, and the work W done on the gas.
(I FOUND THESE ANSWERS ALREADY)
Wenv= 2.79 x10^3
Q= 2.79 x10^3
W= -2.79 x10^3

B) Suppose that subsequent to this heating, 1.80 104 J of thermal energy is removed from the gas isothermally. Find the final volume in terms of the initial volume of the example, V0. (Hint: Use the values in question A. Also note that the initial volume in this exercise is 1.25 V0.)
Vf = ? x V0

Explanation / Answer

Use Boyl's law for gases P1V1 = P2V2
