Which law states that at a constant temperature, the volume of a given mass of a dry gas is inversely proportional to its pressure?

💡 Solution & Explanation

Boyle's law establishes that for a fixed quantity of dry gas maintained at constant temperature, the absolute pressure is inversely proportional to the volume it occupies. Charles's law governs the direct proportionality between volume and temperature at constant pressure, while Gay-Lussac's law relates pressure and temperature at constant volume. This gas law can be mathematically expressed as PV equals a constant. It reflects the fundamental kinetic behavior of ideal gas molecules under varying compression.
