Question 945 Deck General

The correct answer is D) liquified state. The vapor pressure of a gas is defined as the pressure necessary to keep the gas in a liquefied state. At a given temperature, the vapor pressure of a gas is the pressure that must be exerted to maintain a dynamic equilibrium between the gas phase and the liquid phase of the substance. This means that the vapor pressure is the pressure required to prevent the gas from condensing into a liquid. The other answer choices are incorrect because they do not accurately describe the purpose of vapor pressure. Vapor pressure is not related to the inert, soluble, or solid states of a gas.
