Basic States
The three main states of matter found on Earth.
What are solid, liquid, and gas?
Particles in this state are tightly packed and vibrate in place.
What is solid?
Solid to liquid.
What is melting?
This must be added to change a solid into a liquid.
What is heat (or energy)?
The state of matter created at extremely low temperatures.
What is Bose-Einstein condensate?
The state with the highest density and least particle motion.
What is solid?
Particles in a liquid can do this but remain close together.
What is flow or slide past each other?
Liquid to gas.
What is evaporation or vaporization?
Phase changes that absorb energy.
What are melting, vaporization, and sublimation?
This describes how matter changes state.
What is a physical change?
The state of matter with a definite volume but no definite shape.
What is liquid?
In a gas, particles move in these directions.
What is all directions or randomly?
Gas to liquid.
What is condensation?
Phase changes that release energy.
What are condensation, freezing, and deposition?
This high-energy state of matter is made up of positively charged ions and free electrons.
What is plasma?
The state where particles move freely and expand to fill their container.
What is gas?
The force that holds particles together in solids and liquids.
What are intermolecular forces?
Solid to gas without becoming a liquid.
What is sublimation?
The flat portions on a heating curve represent this.
What is a phase change?
This diagram shows how temperature and pressure determine the state of matter.
What is a phase diagram?
The fourth state of matter, made of ionized particles and found in stars.
What is plasma?
The kinetic energy of particles is directly related to this property.
What is temperature?
The reverse of sublimation.
What is deposition?
The amount of energy needed to melt one gram of a substance.
What is heat of fusion?
The point at which all three states of a substance coexist.
What is the triple point?
