Option 1 is correct, i.e. Henry's law. Henry’s law, states that the weight of a gas dissolved by a liquid is proportional to the pressure of the gas upon the liquid. The law, which was first formulated in 1803 by the English physician and chemist William Henry, holds only for dilute solutions and low gas pressures. Extra facts: Charles' law: A law stating that the volume of an ideal gas at constant pressure is directly proportional to the absolute temperature. Boyle's law: A law stating that the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature. Newton's law: Newton’s first law: states that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force. Newton’s second law: States that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it. Newton’s third law: states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction.
