The basic idea is that in a solid, the atoms attract one another so strongly that they maintain their relative positions. In a fluid (liquid or gas) the attraction is less, so the atoms are free to move around.
Fluids are substances that flow. Liquids flow, gases flow, and ionized gases (plasmas) flow. Thus, they are all fluids.
Fluids have the ability to flow. Fluids are Liquids and Gasses.
Flow
A fluid is any substance that can flow. Since liquids and both flow, they are fluids.
Fluids are substances that have the tendency to flow. Gases and liquids are both fluids because they both flow.
Second grade fluids are fluids that flow through a parallel plate. The fluids go through the parallel plate horizontal.
Because the solid can be made to flow, or move so it is called as fluids
yes they are all fluids as they all flow
Yes, that's what "fluid" means - that the substance in question can flow.
Because they can flow.
