question 3 of 25 what would cause a balloon to expand if taken to the top of a mountain? a. increased amount of molecules b. lowered temperature c. lowered pressure d. increased molecular collision
Answer
Brief Explanations:
As altitude increases (such as going to the top of a mountain), atmospheric pressure decreases. According to Boyle's law for a given amount of gas at constant temperature, pressure and volume are inversely - related. So, when the external pressure on the balloon decreases, the gas inside the balloon expands to equalize the pressure, causing the balloon to expand.
Answer:
C. Lowered pressure
