Example: <span>PV = k Where P is pressure of the gas and V is volume of the gas and k is constant. It easily derived by the equation above. Boyle’s law states that when the gas amount and its temperature the same or held constant, within a closed system, the relation of the pressure exerted by the gas is inversely proportional to its volume. So in the situation, the pressure increases, so its volume decreases.</span>
