What does Boyle's law allow you to calculate?

Boyle's law specifically describes the relationship between the pressure and volume of a gas at constant temperature. According to this law, when the volume of a gas increases, its pressure decreases, and vice versa, as long as the temperature remains constant. This inverse relationship can be mathematically expressed as ( P_1V_1 = P_2V_2 ), where ( P ) represents pressure and ( V ) represents volume. This law is fundamental for understanding gaseous behavior in various scientific and practical applications.

In contrast, the other options address different aspects of gas behavior or concepts that do not apply to Boyle's law. For instance, changes in pressure and temperature pertain more to the combined gas law or ideal gas law. The volume and temperature relationships refer to Charles's law, while mass and volume relationships typically relate to density and involve different principles altogether. Hence, Boyle's law allows for clear calculations between pressure and volume, making understanding this relationship essential for studies involving gases.
