States of Matter
What is a solid?
when a solid turns into a liquid.
What is melting.
What is viscosity?
What are two forms of vaporization.
has a definite volume but not a definite shape.
what is a liquid?
The change of state from a gas to a liquid.
What is condensation?
Energy that is stored.
What is potential energy?
Is the amount of space that matter fills?
What is Volume?
Has neither a definite shape or volume.
What is a gas?
The process by which molecules at the surface of a liquid absorb enough energy to change into a gas.
what is Evaporation.
The inward force of molecules in liquids that bring molecules on the surface closer together.
What is Surface tension?
The temperature at which water starts to boil.
what is 212 degrees Fahrenheit or 100 degrees Celsius?
Solids that are useful for manufacturing because they don't melt at a distinct temperature (rubber, plastics, glass)
What are amorphous solids?
The change in state from a liquid to a solid.
What is freezing?
Energy in motion.
What is Kinetic energy?
the temperature at which water freezes.
what is 32 degrees Fahrenheit/0 degrees Celsius.
Solids made out of crystals (salt, sugar, snow), and melt at a distinct temperature.
what are crystalline solids?
when a solid changes directly into a gas without becoming a liquid first.
What is sublimation?
The total kinetic and potential energy of all particles in an object.
What is thermal energy?
The measure of the average kinetic energy of the particles in a substance.
what is Temperature?
