Question
If a balloon is heated, what happens to the volume of the air in the balloon if the pressure is constant?A.It increases.B.The change cannot be predicted.C.It decreases.D.It stays the same.
Solution
The answer is A. It increases. This is due to Charles's Law, which states that the volume of a gas increases as the temperature increases, provided the pressure is kept constant. This is because heating the gas causes the particles to move faster and occupy a larger space, thus increasing the volume.
