Solids
the particles are arranged in an orderly, repeating, three-dimensional pattern called a _____ lattice
What is crystal
When a solid converts to a liquid
What is vaporization
Temperature of absolute zero (Celsius)
What is -273.15°C
The pressure required to liquefy a gas at its critical temperature
What is critical pressure?
When a liquid becomes a solid
What is freezing?
Substances that can flow
What are gas particles
The energy an object has because of its motion
What is kinetic energy?
The change of a from solid to a vapor without passing through the liquid state
What is sublimation?
This reflects the orderly arrangement of their particles and the fixed locations of their particles
What is the general properties of solids?
Boiling points are dependant on this
What is the strength of intermolecular forces?
T/F: Gas particles travel in random curved paths
The boiling point increases
What is a higher external pressure?
All matter consists of tiny particles that are in constant motion
What is the kinetic theory?
two or more different molecular forms of the same element in the same physical state.
What is an allotrope?
When vaporization occurs at the surface of a liquid that is not boiling
What is evaporation?
A measure of the force exerted by a gas above a liquid
What is vapor pressure?
When a liquid is heated to a temperature at which particles throughout the liquid have enough kinetic energy to vaporize
What is liquid boiling?
This is directly proportional to the average kinetic energy of the particles of a substance
What is the Kelvin temperature of a substance?
This makes allotropes' properties different
The temperature at which the vapor pressure of the liquid is just equal to the external pressure on the liquid
What is boiling point?
This increases vapor pressure
What is an increase in temperature of a contained liquid?
Particles have no kinetic energy in this state
What is absolute zero?
Describes the only set of conditions at which all three phases can exist in equilibrium with one another
What is a triple point phase diagram?
