Chapter 22 States of Matter
Matter
Anything that has mass and takes up space
Thermal Energy
Energy from heat
Heat
Energy that is transformed as a consequence of temperature differences
pressure
Force/area
Plasma
A fourth state of matter distinct from solid or liquid or gas and present in stars and fusion reactors.
Viscosity
A measure of a fluid's thickness or resistance to flow.
Temperature
A measure of the average energy of motion of the particles of a substance.
Liquid
A state of matter that has a definite volume but no definite shape.
Gas
A state of matter with no definite shape or volume
Condensation
Change in state from a gas to a liquid
Freezing
Change of state from a liquid to a solid
Archimedes principle
States that the buoyant force is equal to the weight of the fluid displaced by an object.
Vaporization
The change of state from a liquid to a gas
Melting
The temperature at which a solid changes to a liquid.
pascals principle
When force is applied to a confined fluid, the change in pressure is transmitted equally to all parts of the fluid
Solid
a state of matter that has definite shape and volume
Surface Tension
the uneven forces acting on the particles on the surface of a liquid
buoyant force
upward force exerted by a fluid on an immersed objec
