when the pressure of gas is decreased, the volume increases. this relationship between pressure and volume is called Boyle's law. So, at constant temperature, the answer to your answer is: the volume decreases in the same ratio as the ratio of pressure increases. ... But you won't get any change in volume

A concave meniscus develops when the liquid molecules are drawn to those in the vessel, which is what you usually would see. It occurs with water and a tube made of glass. A convex meniscus occurs because, as with mercury and glass, the molecules have a greater attraction to each other than to the container.
