Fluids

Summary

• Fluids are substances with no fixed shape.
• Density: p=m/V
• Difference between states of matter is how strongly their particles interact.
• Object floats when density is less than surrounds density.
• Ideal fluid has no viscosity and is incompressible.
• Density changes with temperature and pressure.
