So, the difference between liquids and fluids boils down to their viscosity as fluids have a higher viscosity such as oils than liquids. Fluids can be gases also whereas liquids arte altogether different than gases. What about dry sand, flour, baking soda, ground coffee beans, salt… these are all solids, yet they flow and fill a container because they are made of tiny grains or crystals.
Could one say that they are fluid but not liquid? Your email address will not be published.

Gasses are also fluids, which form compressible fluids. They do flow as a result of the difference in friction between two points, but at the same time, they can be compressed or extended.
Their density is fluctuating with the pressure. As a consequence, fluids consist of 2 mutually exclusive classes of compressible and incompressible fluids. Liquids are incompressible fluids and thus constitute a subset of the more general word fluid.
A form of matter that can flow from one place to another through any opening without showing any traits of rigidity. A phase of matter which depends on the prevailing temperature and pressure of a particular substance.
It may or may not have some level of viscosity. It has volume but no shape. Reference to gas and liquid. No gas, only liquids. Water, honey, air, mercury, gasoline, etc. Water, blood, milk, wine, coffee, etc.
Gas pressure is measured in pascals. During the process of becoming a butterfly, the entire caterpillar will break down into a liquid.
The distinction is useful for scientists and engineers who want to thoroughly understand how matter works. Scientists have developed precise definitions describing what they mean when they talk about fluids; this is necessary to avoid confusion. A fluid is a substance that lacks rigidity; it can flow from place to place and through holes or gaps in containers. Jelly is an unusual fluid because its thickness depends on how hard you stir it.
Liquid is the state of matter of a substance at temperatures and pressures intermediate between those of its solid and gas forms. Like solids and unlike gases, liquids are relatively incompressible; that is, squeezing them does not make them smaller in volume.
