A balloon is inflated at sea level where the atmospheric pressure is 101.3 kPa. What will happen to the balloon as it rises into the atmosphere and the pressure decreases? The volume will decrease. The balloon will burst. The volume will increase. The balloon will shrink.

## Step 1<br />This problem is based on Boyle's Law, which states that the pressure and volume of a gas have an inverse relationship when the temperature is held constant. This means that if the pressure decreases, the volume of the gas will increase, and vice versa.<br /><br />## Step 2<br />In this case, the balloon is inflated at sea level where the atmospheric pressure is 101.3 kPa. As the balloon rises into the atmosphere, the pressure decreases.<br /><br />## Step 3<br />According to Boyle's Law, as the pressure decreases, the volume of the balloon will increase. This is because the gas inside the balloon will expand to fill the larger volume available due to the decrease in pressure.
