A theory explaining the state of matter, based on the concept that all matter consists of tiny particles that are in constant motion.
What is kinetic theory?
100
The conversion of a liquid to a gas or vapor is called vaporization.
True or False
100
• Particles are tightly packed together • Often in an orderly arrangement • Definite shape and volume • Almost incompressible • Expand only slightly when heat
What are the characteristics of solids?
100
It also rises
When the kinetic energy in a gas rises, what happens to the temperature?

The particles in a gas are considered to be small, hard spheres with an insignificant volume.
What are the characteristics of gas particles?
200
A measure of the force exerted by a gas above a liquid is called vapor pressure.
What is vapor pressure?
200
The smallest group of particles within a crystal is known as a unit cell.
What is a unit cell?
200
As a substance is heated, its particles absorb energy, some of which is stored within the particles.
How does Kinetic Energy relate to temperature?
200
A phase diagram in physical chemistry, engineering, mineralogy, and materials science is a type of chart used to show conditions (pressure, temperature, volume, etc.) at which thermodynamically distinct phases occur and coexist at equilibrium.
What are phase diagrams?
300
Gas pressure is the result of billions of rapidly moving particles in a gas simultaneously colliding with an object.
What is gas pressure?
300
Particles are free to flow, indefinite shape (i.e. Takes shape of container), it has a definite volume, almost incompressible, expand slightly when heat.
What are the characteristics of liquids?
300
Occurs at temperatures and pressures below a substance's triple point in its phase diagram.
When does sublimation occur?
300
• Space between particles • Indefinite shape (i.e. takes shape of container) • Indefinite volume • Can be compressed
What are the characteristics of gases?
300
Atoms, ions, and molecules can react to form products when they collide, provided that the particles have enough kinetic energy. All collisions between particles in a gas are perfectly elastic.
What is collision?
400
Energy that a body possesses by virtue of being in motion.
What is kinetic energy?
400
After vaporization the surface of a liquid that is not boiling is called evaporation.
DOUBLE JEOPARDY! What is evaporation?
400
In a crystal structure the particles are arranged in an orderly, repeating, three-dimensional pattern called a crystal lattice.
How is a crystal structure?
400
As the kinetic energy increases the attraction between molecules decreases.
What is the best description of the relationship between states of matter and kinetic energy?
400
Rate of evaporation if a liquid equals the rate of condensation An increase in temperature of a contained liquid increases the vapor pressure Molecules have increased kinetic energy
What is equilibrium?
500
The energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
What is Potential energy?
500
101.3KPa or 1 atmosphere (atm)
What is the boiling point?
500
Sublimation is the phase transition of a substance directly from the solid to the gas phase without passing through the intermediate liquid phase.
What is sublimation?
500
yes
Does gas have the most kinetic energy?
500
Endothermic
Double Jeopardy! Is sublimation endothermic or exothermic?
