Boyle's Law states when pressure increases, then the volume must __ be constant stay the same increase decrease

## Step 1<br />Boyle's Law, named after Robert Boyle, is a fundamental principle in physics that describes the relationship between the pressure and volume of a gas at constant temperature. <br /><br />## Step 2<br />According to Boyle's Law, the pressure of a gas is inversely proportional to its volume, provided the temperature remains constant. This means that if the pressure increases, the volume must decrease to maintain the balance.<br /><br />## Step 3<br />Therefore, when the pressure increases, the volume must decrease.
