Question

boyle’s law (page 70)

1. if the temperature and number of particles of gas in a cylinder do not change, and the volume of the cylinder is reduced by half, the pressure of the gas will be ______ as the original pressure.

Explanation:

Boyle's Law defines an inverse relationship between the pressure and volume of a gas (when temperature and the amount of gas are constant), expressed as $P_1V_1 = P_2V_2$. If volume is reduced to half ($V_2 = \frac{1}{2}V_1$), solving for $P_2$ shows pressure doubles.

Answer:

twice (or double)
