This state of matter has the least thermal energy.

What is solid

100
This is the ability to do work or cause change
What is energy
100

The formation of clouds is an example of this change in matter.

What is condensation

100
The force of particles and whatever they bump into creates _____________
What is pressure.
100

Which gas law has variables that are directly proportional to each other and form a straight line that crosses the origin when graphed?

What is Charles's Law

200
Matter that has a fixed volume and shape
What is Solid
200
This is the energy of motion
What is kinetic energy
200
The change from a solid state to a liquid state is called
What is melting
200
This is the law that states that while the temperature of a gas is held constant, then as the volume of a gas increases then the pressure decreases
What is Boyle's law
200

When Boyle's Law is graphed, the line formed in curved and does NOT go through the origin.  This relationship where one variable increases while the other decreases is called ______________ ____________.

What is inversely proportional

300
This state of matter does not have a fixed volume or shape.
What is gas
300
The average kinetic energy of an individual particle is called
What is temperature
300
The opposite of vaporization
What is condensation
300
The more gas particles there are, the greater the _______________
What is pressure
300

When a substance melts, the particles need to ____________ thermal energy.

What is gain

400
Matter that does not have a fixed shape, but does have a fixed volume.
What is liquid
400
The total kinetic and potential energy in a sample of matter is called
What is thermal energy
400
The process in which particles in a solid gain enough thermal energy to change directly into a gas
What is sublimation
400

If the volume of a gas is held constant, increasing the temperature of the gas will ______________ it’s pressure.

What is increase

400

When the particles start to slow down and take a fixed position, this change of state is occurring.

What is freezing

500

This state of matter has particles with the most thermal energy.

What is gas

500
If particles have more kinetic energy then they have more _____________________.
What is thermal energy
500

What is the difference between evaporation and boiling?

What is evaporation occurs only at the surface of the liquid and can happen at any temperature, while boiling occurs both at the surface and below the surface of a liquid and happens at a specific temperature.

500
This is the law that states that as the pressure of a gas is held constant, then as the temperature increases the volume will also increase
