The state of matter of these molecules.
What is a liquid?
200
Any process that releases energy, or heat.
What is Exothermic?
200
These alloys have a high plasticity under normal heating conditions, but when heated up they revert back to their original shape.
What are Shape Memory Alloys?
300
This form of matter has a no definite shape but does have a definite volume.
What is a liquid?
300
This type of energy is considered at rest, or "loaded", ready to be used.
What is potential energy?
300
The phase change from a solid to a liquid is called this.
What is melting?
300
The state of matter of these molecules.
What is a solid?
300
The moment when a gas and liquid are considered indistinguishable.
What is the critical point?
300
Normal stress is any force applied perpendicular to a surface, while this stress is force applied parallel to the surface.
What is Shear Stress?
400
This matter has no definite shape and no definite volume.

What is sublimation?
500
The changing of a gas directly to a solid.
What is deposition?
500
This law states when you increase the pressure of a gas, the volume decreases; and if you decrease the pressure of a gas, the volume of that gas increases.
