True or False: Plasma is considered a state of matter.
True
Fill in the blank: A ________ has a definite shape and volume.
solid
Which state of matter has a definite volume but no definite shape?
Liquid
What is the term for a substance that can exist in multiple states of matter?
Phase
True or False: Gases have a definite shape and volume.
False
What is the process called when a solid turns directly into a gas?
Sublimation
What happens to the particles in a substance when it is heated?
They gain energy and move faster.
What is an alloy?
A mixture of two or more metals.
Which of the following is an example of an alloy: Brass, Iron, or Aluminum?
Brass
True or False: Alloys usually have properties that are superior to their component metals.
True

Iron
Fill in the blank: The process of mixing metals to create an alloy is called ________.
Alloying
What state of matter is characterized by particles that are far apart and move freely?
Gas
In which state of matter do particles vibrate but do not move freely?
Solid
What is the term for the change of state from liquid to solid?
Freezing
What is the primary benefit of using alloys in construction?
Strength and durability
Which state of matter is most commonly found in the universe?
Plasma
True or False: Metals are usually good conductors of electricity.
True
What is the effect of pressure on the state of matter?
