According to Boyle's Law, when the pressure of a gas decreases (assuming temperature remains constant), the volume of the gas increases. Specifically, Boyle's Law states that the product of pressure and volume is constant for a given amount of gas at a constant temperature.
Mathematically, this can be expressed as:
\[ P_1 \times V_1 = P_2 \times V_2 \]
If the pressure decreases to half its original value (i.e., \( P_2 = \frac{1}{2} P_1 \)), the volume must increase to twice its original value (i.e., \( V_2 = 2 V_1 \)) to maintain the equality.
So, the correct response is:
**The volume increases to twice its original value.**
