Physical Science Chapter 3 - States of Matter Test Review

A set of vocabulary flashcards covering key concepts from Physical Science Chapter 3 on the states of matter.

Evaporation

The change of state from a liquid to a gas.

Viscosity

The resistance of a fluid to flow.

Pascal's Principle

A contained fluid exerts pressure equally in all directions.

Boyle's Law

As the pressure of a gas at constant temperature decreases, its volume increases.

Kinetic Theory

States that the higher the temperature, the faster the particles that make up a substance move.

Buoyant Force

The upward force exerted on an object immersed in or floating on a fluid.

Sublimation

The change of a substance from a solid directly to a gas.

Condensation

The process of a gas becoming a liquid.

Freezing Point

The temperature at which a substance changes from a liquid to a solid.

Pressure

Calculated by dividing force by the area over which the force is exerted.

Density

Mass per unit volume of an object, determining if it sinks or floats.

Liquid

A state of matter with a definite volume, but no definite shape.

Gas

A state of matter that expands to fill its container.

Fluid

A substance that flows, includes liquids and gases.

Archimedes' Principle

States that the buoyant force on an object is equal to the weight of the fluid displaced.

Kinetic Energy

The energy an object possesses due to its motion.

Bernoulli's Principle

Describes the relationship between the velocity and pressure of a fluid.

Hydraulics

The use of liquid under pressure to transmit force.

Energy Transfer

Required for any change of state to occur.

Solid

A state of matter with a definite shape and a definite volume.
