How fast a fluid "runs".

• Change of State

• Flow Rate

• Density

• Buoyancy

Any substance that flows.

• Fluid

• Solid

• Viscosity

• Buoyancy

Mrs. Quinton made a list of fluids that have a high viscosity: molasses, honey, water, and syrup. Which fluid doesn't belong?

• Molasses

• Honey

• Water

• Syrup

The viscosity of a gas increases as its heated and decreased as it is cooled. The opposite occurs in a liquid.

• True

• False

The buoyant force acting on an object that is submerged in a fluid equals the weight of the fluid that is displaced by the object. This describes which principle?

• Quinton's Principle

• Archimedes' Principle

• Aristotle's Principle

• Pascal's Principle

This is the measurement of the amount of space that is occupied by a substance.

• Volume

• Mass

• Area

• Force

This is achieved when an object neither rises nor sinks in a fluid. This allows fish to stay at a constant depth of water.

• Positive buoyancy

• Neutral buoyancy

• Negative buoyancy
