Which law states that the volume of a gas is inversely proportional to its pressure at constant temperature?
Boyle's Law
Charles's Law
Avogadro's Law
Gay-Lussac's Law
Boyle's Law
Boyle's Law states that the volume of a given mass of a dry gas is inversely proportional to its pressure when the temperature is kept constant. This means that if the pressure of a gas increases, its volume decreases proportionally, and vice versa.

Squeezing a flexible, half-filled water balloon with your hands reduces its volume, compressing the air inside and causing the pressure to rise significantly.

At the molecular level, gas pressure arises from molecules colliding with the container walls. Decreasing the container volume forces molecules closer together, increasing collision frequency per unit area and raising the pressure.
Applies to a fixed mass of gas at constant temperature.
Graph of pressure versus volume results in a hyperbola (isotherm).
Mechanism of human respiration (lungs expansion and contraction)
Working of a medical syringe when drawing or injecting liquids
Conditions: Constant temperature (T) and number of moles (n).
Option B (Charles's Law) describes volume directly proportional to temperature at constant pressure.
A is correct тАФ Boyle's Law states that gas volume is inversely proportional to its pressure at constant temperature.
For competitive exams, always remember that isotherms represent curves plotted at constant temperature under Boyle's Law.
