what are the differences in observable properties between a gas and a liquid?

First, we know that a gas has no definite volume or shape; a gas will fill whatever volume is available to it. Contrast this to the behavior of a liquid, which always has a distinct upper surface when its volume is less than that of the space it occupies.

Characteristics of Liquids Liquids have definite volume, but indefinite shape. They are free to form droplets and puddles when they are not inside a container. When a liquid is inside a container, it will take its shape. Unlike gases, a liquid will not change its volume to spread out and completely fill a container.

The Difference between oil and gas is that the term oil refers to hydrocarbon mixtures that are liquid at room temperature, whereas gas is a mixture of gas formed from the fossil remains buried deep in the Earth. ... Oil is an unctuous flammable substance which is not water soluble, whereas gas is an aeriform fluid.

Particles in a: gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.

However, an important difference exists between them; liquid describes a state of matter--as do "solid" and "gaseous"--whereas a fluid is any substance that flows. Nitrogen gas, for example, is a fluid, whereas orange juice is both a liquid and a fluid.

Properties of Matter: Gases. Gas particles spread out to fill a container evenly, unlike solids and liquids. Gas is a state of matter that has no fixed shape and no fixed volume. Gases have lower density than other states of matter, such as solids and liquids.

A gas does not have a definite mass. ... A gas does not have a definite volume. A gas does not always weigh the same or take up the same amount of space. However, like a liquid, a gas will always take the shape of its container, no matter the size or shape of that container.

Gases have three characteristic properties: (1) they are easy to compress, (2) they expand to fill their containers, and (3) they occupy far more space than the liquids or solids from which they form. An internal combustion engine provides a good example of the ease with which gases can be compressed.

A gas has one defined state at room temperature whereas a vapour is a substance that is in gaseous and liquid equilibrium at room temperature, at a given pressure. A gas can also refer to a single element of matter with its own unique physical and chemical properties, for example oxygen, nitrogen and neon.

Solid is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter adapts to the shape of its container but varies only slightly in volume; and gas is the state in which matter expands to occupy the volume and shape of its container.

A solid has definite volume and shape, a liquid has a definite volume but no definite shape, and a gas has neither a definite volume nor shape.

The molecules of any gas are relatively are far apart from each other while molecules of liquid are are relatively close together . ... by increasing the pressure on gas 2.by lowering the temperature of gas.

Oil is a liquid, but propane is a gas. Liquids are fluid, like water, but gases seem to have no visible appearance, like air. Gas is a general term for air-like substances, but there are specific gases that can be ignited and used for heating. You can choose between natural gas and propane for your home heating system.

Air is a gas while water is a liquid. Air is compressible while water is for all purposes non compressible. Water is H2O with some dissolved solids and gases while air is a mixture of all gases with some water in the form of vapor.

2) Liquids – have no definite shape but have a definite volume, and they are not easily compressible. ... 3) Gases – a gas has no definite shape, it takes the shape of the container that holds it. Gases are easily compressible. Molecules are separated by distances that are large compared with the size of the molecules.
