100
The standard pressure in kPa
What is 101.3 kPa?
100
According to the kinetic theory, the collisions of the particles of this phase are completely elastic.
What is gas?
100
The only phase that does not have intramolecular attractions between particles.
What is gas?
100
States that all phases are in constant motion.
What is the kinetic theory?
100
The point at which a solid changes into a liquid.
What is melting point?
200
1 atm in mm Hg.
What is 760 mm Hg?
200
This happens to the average kinetic energy as temperature increases.
What is increases?
200
The only phase that doesn't flow.
What is solid?
200
All three phases come together here on a phase diagram.
What is triple point?
200
Vaporization at the surface of a liquid that is not boiling.
What is evaporation?
300
The device that measures atmospheric pressure.
What is a barometer?
300
When a gas is heated, some of the energy becomes kinetic and the rest becomes this.
What is potential?
300
The smallest group of particles within a crystal structure that retains the shape of the crystal.
What is unit cell?
300
This temperature scales is directly proportional to average kinetic energy.
What is Kelvin?
300
The change of solid directly into a vapor.
What is sublimation?
400
The pressure of the force exerted by a gas above a liquid.
What is vapor pressure?
400
The energy an object has due to its motion.
What is kinetic energy?
400
A solid that lacks internal structure.
What is amorphous solid?
400
This happens to the temperature of a boiling liquid as energy is added.
What is nothing?
400
The temperature at which the vapor pressure of a liquid is equal to external pressure.
What is boiling point?
500
With increasing altitude, this happens to boiling point.
What is decreases?
500
These are equal if a dynamic equilibrium exists between the liquid and gas phases.
What are rates of evaporation and condensation?
500
Two or more different forms of the same element in the same physical state.
What are allotropes?
500
Crystals are classified into this many crystal systems.
What is seven?
500
This happens to the temperature of a liquid as it evaporates.
What is decreases?
