100
This is the force of a gas's outward push divided by the area of the walls of the container.
What is pressure?
100
This is the opposite of vaporization.
What is condensation?
100
This is the amount of space that a gas takes up.
What is volume?
100
This is the change from liquid to solid, or the reverse of melting.
What is freezing?
100
This affects the boiling point of a substance.
What is atmospheric pressure?
200
This gas law shows the relationship between volume and pressure of a gas.
What is Boyle's law?
200
This occurs when a liquid becomes a gas.
What is vaporization?
200
When the temperatue is constance, the volume of a gas will do this as the pressure decreases.
What is increases?
200
In a flexible container, when the temperature of a gas increases, the volume of the gas will do this.
What is increase?
200
The common state of matter that does not have a definite shape or a definite volume.
What is a gas?
300
A graph that shows that the pressure of a gas varies inversely with its volume under constant temperature demonstrates this law.
What is Boyle's law?
300
Particles are packed closely together, but they can move past each other freely.
What is a liquid?
300
Pieces of dry ice become smaller through this process.
What is sublimation?
300
This occurs when particles in a gas lose enough thermal energy to form a liquid.
What is condensation?
300
The measure of the average energy of motion of the particles of a substance.
What is temperature?
400
According to Charles's law, whent he temperature of a gas increases at a consant pressure, this increases.
What is volume?
400
This theory states that all particles of matter are in constant motion.
What is kinetic theory?
400
These factors affect the pressure of an enclosed gas.
What are temperature, volume, and the number of particles?
400
This does not change during phase change.
What is temperature?
400
This takes place at the surface of a liquid and occurs at temperatures below the boiling point.
What is evaporation?
500
P1 V1/T1 = P2 V2/T2
What is the combined gas law?
500
The number used to convert celsius to kelvin.
What is 273?
500
The mathematical equation that expresses the relationship that the pressure of a gas is sdirectly proportional to its temperature in kelvins.
What is P1/T1 = P2/T2
500
During this change, the system releaes energy to its surroundings.
What is exothermic?
500
During this change, the system absorbs energy from its surroundings.
What is endothermic?
