A hot air balloon descends from a pressure of 380 mm Hg to 760 mm Hg and at the high altitude has a volume of 1,000 cubic meters. If the temperature starts at 50 degrees C and changes to 25 degrees C, the new volume will be:

Question

a. 100.0 x 50 x 760/25 x 380
b. 100.0 x 50 x 25/760 x 380
c. 100.0 x 760 x 323/380 x 298
d. 100.0 x 25 x 760/50 x 380
e. none of these

Answer 1

V2 = 1000 * 380/760 * 25/50

e. None of these.
