Chapter 2 Flashcards
(22 cards)
Crystalline solid
A solid that is made up of crystals in which particles are arranged in a regular, repeating pattern
Solid
A state of matter that has a definite shape and a definite volume
Amorphous solid
A solid made up of particles that are not arranged in a regular pattern
Liquid
A state of matter that has no definite shape but has a definite volume
Fluid
any substance that can flow
Surface tension
The result of an inward pull among the molecules of a liquid that brings the molecules on the surface closer together
Viscosity
A liquids resistance to flowing
Gas
A state of matter with no definite shape or volume
Pressure
The force pushing on a surface divided by the area of that surface
Melting
The change in state from a solid to a liquid
Melting point
The temperature at which a substance changes from a solid to a liquid
Freezing
The change in state from a liquid to a solid
Vaporization
The change of state from a liquid to a gas
Evaporation
The process by which molecules at the surface of a liquid absorb enough energy to change to a gas
Boiling
Vaporization that occurs at and below the surface of a liquid
Boiling point
The temperature at which a liquid boils
Condensation
The change in state from a gas to a liquid
Sublimation
The change in state from a solid directly to a gas without passing through the liquid state
Charles’s Law
The principle that describes the relationship between the temperature and volume of a gas at constant temperature
Directly proportional
A term used to describe the relationship between two variables whose graph is a straight line passing through the point (0,0)
Boyle’s law
The principle that describes the relationship between the pressure and volume of a gas at a constant temperature
Inversely proportional
A term used to describe the relationship between two variables whose product is constant
