Fluids Lecture Review

Flashcards reviewing key concepts about fluids, including their phases, properties, and density.

What are the three phases that all matter is commonly divided into?

Solid, Liquid, and Gas

Describe a solid's shape and volume.

Definite shape and volume

Describe a liquid's shape and volume.

Definite volume; takes the shape of its container, virtually incompressible

Describe a gas's shape and volume.

No definite volume or shape, compressible

What are solids and liquids collectively called?

Condensed matter

What are liquids and gases collectively called?

Fluids

Define a fluid.

A substance that can flow

What holds the particles of a solid together?

Interatomic forces

How do solids respond to external forces?

They can be elastically deformed

How do fluids respond to a force?

They have little or no elastic response, instead causing it to flow

What is density a physical property of?

All matter, including fluids

Define density in the context of matter.

A measure of the compactness of matter

What is the formula for density?

Density = mass/volume

What are common units for density?

g/cm3, kg/m3
