Boyle's Law describes the inverse relationship between the pressure and volume of a gas when the temperature is kept constant. This means that if the volume of an ideal gas decreases, the pressure increases, provided the temperature remains unchanged. The mathematical representation of Boyle's Law is PV = k, where P is pressure, V is volume, and k is a constant for a given amount of gas. This principle is derived from the ideal gas law and highlights how gases will compress or expand in response to changes in pressure while maintaining a steady temperature.

The other laws mentioned relate to different aspects of gas behavior. Charles's Law, for example, explains the relationship between volume and temperature, showing that the volume of a gas increases with an increase in temperature, keeping pressure constant. Avogadro's Law deals with the relationship between the volume of a gas and the number of moles at constant temperature and pressure, while Dalton's Law pertains to the total pressure exerted by a mixture of gases. Each of these laws encapsulates unique principles governing gas behaviors, but Boyle's Law specifically addresses how volume and pressure interact under isothermal conditions.
