Fluids Flashcards
What is a fluid?
A FLUID is a substance that has the capacity to flow and assume the form of the container into which it has been poured.
Explain the particles in a liquid:
the particles in a liquid are close together and are held together by weak forces of attraction. The particles can slide all over each other and take on the shape of their container.
Explain the particles in a gas:
the particles of a gas are much further apart
and are NOT bound together by forces of attraction. They move in all directions and take up its whole container.
Can a liquid be a fluid?
Yes, A liquid can be a fluid : water assumes the shape of a glass because the forces of attraction in a liquid are not as strong as in a solid.
Can I gas be a fluid?
Yes, A gas can be a fluid: no forces of attraction exist between the particles in a gas. Air moves around in the respiratory system, occupying all available space.
If water had sesame seeds mixed into it, would it still be considered as a fluid?
Yes. As you pour the mixture out, the seasame seats would pour with it.
Would toothpaste be a fluid?
Yes because if you pour a lot of toothpaste out into a cup it would take the shape of that cup.
Is sand a fluid?
Sand is NOT a fluid. It does flow, but it is not continuous. It also forms a pile and does not necessarily take the form of it’s container.
What are the two type of fluids?
Compressible (gas) and incompressible (liquid)
What is the definition of a compressible fluid?
Definition: A compressible fluid is a fluid whose volume can change in response to a change in pressure. Gases are compressible fluids
Will gasses take up all the space in a container?
Gases will take up all the space in a given container.
Therefore, if you change the size of the container the gases volume will change.
What is the definition of a incompressible fluid?
Definition: An incompressible fluid is a fluid whose volume cannot be varied. Liquids are incompressible fluids.
What would happen if you put your hand onto a bag of milk?
The milk would reform its self
