Which of the following statements explains what happens to the gas inside a balloon as the external pressure on the balloon decreases and the temperature stays constant?
A. The volume increases.
B. The volume decreases.
C. The molecular speed increases.
D. The molecular speed decrease



The volume will increase because the internal pressure is varies linearly in the volume if the external pressure decrease the internal may increase and also the volume, there is no molecular speed will happen because the temp is remains constant
