What are the charecteristics of a solid?
Definite shape, definite volume, closely packed particles, particles vibrate in place,
-
What are the charecteristics of a liquid?
Definite volume, no definite shape, closely packed particles, particles move freely
-
What are the charecteristics of a gas?
No definite shape or volume, spreads out or squeezes together to fill a container, particles move freely
-
What is a crystaline solid?
The particles form a regular repeating pattern. Has a specific melting point
EX: salt, sugar, snow
-
What is an amourphous solid?
particles are not arranged in a regular pattern, no distinct melting points.
EX: Plastics, glass, rubber
-
What does "fluid" mean?
a substance that flows
-
What is surface tension?
The result of an inward pull among the molecules of a liquid that brings the molecules on the surface closer together.
-
What is viscosity?
A liquids resistance to flowing
-
What is freezing?
When a liquid changes to a solid.
-
What is melting?
when a solid turns into a liquid
-
What is evaporation?
A liquid changes to a gas on the surface.
-
What is boiling?
A liquid changes to a gas.
-
What is condensation?
When a gas changes to a liquid.
-
What is sublimation?
When a solid changes to a gas.
-
What is Boyle's Law?
When the pressure of a gas at a constant temp. increases, the volume of a gas decreases. When the pressure of a gas at a constant temp. is decreased, the volume of the gas increases.
-
What is Charles's Law?
When the temp. of a gas at a pressure is increased, the volume of the gas increases. When the temp. of a gas at constant pressure decreases, the volume of the gas decreases.
