small particles that make up ALL matter; the basic building blocks of life
What are atoms
have a definite shape and definite volume, particles are strongly attracted to each other, particles are locked into their spots
What is a solid?
changing directly from a liquid to a gas by adding heat
What is vaporization?
inherent to an object. It does not change unless the object changes.

What is floating?
The term particles describes lone atoms or combinations of atoms that are bound together in specific ways.
What is a particle?
no definite shape or volume, particles have little to no attraction to each other, takes up any space available
What is a gas?

Condensation
depends on where the object is located.
What is weight?

What is the void?
have a definite volume, but no definite shape, particles are attracted to each other, but are not locked into place, takes the shape of whatever container it is in
What is a liquid?

What is density?
This attraction is called the force of gravity, or _______________.
What is gravitational force
The change of state from a liquid to a solid by cooling.
What is freezing
changing from liquid to vapor, can happen without heat
