Particles, substance, or element
The smallest piece of a substance that is still that substance.
Particle
A measure of the amount of matter
Mass

Draw a particle diagram of water.
Particle diagram should represent a liquid.
A fundamental substance that cannot be broken into simpler substances, the building block of matter.
Element
To increase in volume
Expand
a phase of matter that has no definite shape or volume. Particles of gas fly independently through space.
Gas
During expansion, is there more or less space between the particles?
More
Teacher, use your judgment
A type of matter with a unique particle
Substance
Anything that has mass and takes up space
Matter
the reactant that is present in the least amount in a reaction, which determines when the reaction stops
Limiting factor
During compression in a closed system, are there more/less /or the same number of air particles as before compression?
The same number
In a closed system, does the number of air particles change
No
H2O

Substance
a condition in which a system is experiencing no net change
Equilibrium
amount of force pushing on a certain area.
Pressure
Does compressed air apply more or less pressure on the surrounding area?
What is between air particles?
Nothing
Carbon
Is an example of what?
Element
To decrease in volume
Compress
No particles can enter or leave
