Which statement about the volume and pressure of a gas is the most accurate? Volume of a gas is directly proportional to pressure of that gas in any container. Volume of a gas is inversely proportional to pressure of that gas in any container. Volume of a gas is always greater than pressure of that gas in any container. Volume of a gas is equal to pressure of that gas in any container.
