Name:  _________________________
10th Physical Science 
States of Matter Unit
Across
the resistance by a fluid to flow
______ energy: the total energy of the particles in a material
When particles move fast enough to escape the attractive force of other particles; ex. evaporation & boiling
State of matter where particles are closely packed, constantly vibrating, and maintain a set shape
____ energy: the change from a solid to a gas without the liquid state
State of matter that has no fixed shape and no fixed volume
____ point: the temperature at which the pressure of the vapor in the liquid is equal to the external pressure acting on the surface of the liquid
The ability to cause change; measured in joules
____ Principle: As the velocity of a fluid increases,the pressure exerted by the fluid decreases
_____ Principle: Pressure applied to a fluid is transmitted throughout the fluid
Heat of ______ : the amount of energy needed to change a substance from a solid to a liquid at its melting point
When particles at the surface of a liquid have enough kinetic energy to escape the attractive forces of the liquid
Down
______ change: a physical process in which a substance goes from one phase to another
the ability of a fluid to exert an upward force on an object that is placed in the fluid
When particles slow down and begin to form a liquid from a gas

Heat of ______: the amount of energy needed for the liquid at its boiling point to become a gas
____ Principle: The buoyant force on an object is equal to the weight of the fluid displaced by the object
_______ energy: the energy stored in the bonds between particles in a substance
_____ point: the temperature at which a solid begins to turn into a liquid
4th state of matter; matter consisting of positively and negatively charged particles
force exerted per unit area
_____ point: the temperature at which a solid begins to turn into a liquid
State of matter that can flow, takes the shape of its container and has a set volume
