This depends to some extent on the quantity of liquid or gas that you are trying to measure, but for normal amounts, you would pour the liquid into a graduated cylinder and then read the volume off of the markings on cylinder, and for a gas, the volume is always going to be the same as whatever container it is in, since gas expands or compresses, according to the size of its container.
Yes, Liquid -Liquid displacement is easier than displacement with gas. the liquids cannot be compressible, but gas can. the volume of gas required for displacement is lower than volume of liquid.
The molecules are further apart, thus the gas is less dense and the volume is greater.
a solid has definite volume and shape, a liquid has definite volume but no shape. a gas has nor volume nor shape
because liquid have definite volume but not definite shape and gas does not have definite shape or volume but it fill space
evaporation
Gas has no definite volume because its particles are spread out and can expand to fill any container they are placed in. The other states of matter - solid, liquid, and plasma - have a definite volume.
During evaporation, molecules escape the liquid surface into the air as gas. This conversion from liquid to gas reduces the volume of the liquid as it evaporates. However, the total volume of the system remains constant since the gas molecules occupy the space above the liquid.
Matter in the liquid state can take the shape of a container. However, a liquid has a definite volume. On the other hand, a gas can do both, that is take the shape and volume or size of a container.
The are a couple of differences: First, the particles in a gas are more loosely packed than in a liquid. Second, a liquid has no definite shape but definite volume; a gas has no definite volume and no definite shape.
You can't change volume of a liquid. But only gas it's easy to change
The buoyant force on an object in a liquid or gas has the same magnitude and the opposite direction of the weight of the liquid or gas displaced by the object. So basically, all you need to know is the weight of the displaced gas or liquid and the direction of gravity. The weight of the displaced gas or liquid can be derived from the density of the gas or liquid, the volume displaced, and the gravitational acceleration (weight = mass x gravity, and mass = density x volume). If the object is completely submerged, the volume of displaced liquid or gas is the same as the volume of the object minus the volume of the liquid or gas that enters the object (if the object is, for example, a sponge or a submarine with holes in it).
