Problem
A weather balloon containing a fixed amount of ideal gas is released at ground level where the air pressure is 1.0×105Pa and the gas temperature is 290K. After rising to a higher altitude, the external pressure on the balloon decreases to 5.0×104Pa while the temperature of the gas remains nearly the same. Which of the following best describes what happens to the volume of the gas inside the balloon?
(a) It increases to about four times its original value.
(b) It remains approximately the same.
(c) It increases to about twice its original value.
(d) It decreases to one-half its original value.
