A balloon originally has a volume of 4.39L
at 44 C and a pressure of 729 torr. What temperature must the balloon be cooled to to reduce its volume to 3.78L at the same pressure?
(A) 38 C
(B) 72.9 C
(C) 0 C
(D) 546 C
(E) 273 C
Is the correct answer (A), 38 C?

Convert deg. C to deg. K, then substitute into the Combined Gas Law:
P1V1/T1 = P2V2/T2
Solve for V2.
Your answer is not correct.
