Matter Basics
"The building blocks of matter"
atoms
State of matter that the particles are highly organized and very close together:
solid
The amount of matter in a substance:
mass
Anything that has mass and volume and made up of atoms.
matter
What state of matter is water at 25*C?
liquid
Atoms make up _________ , and each one has its own properties that differentiate them one another.
elements
In this state of matter, particles flow past each other and take the shape of their container.
liquid
The amount of space something takes up:
volume
The amount of energy a substance has is its:
temperature
Write the density formula.
D=M/V
Two elements that combine together form a:
compound
This state of matter has the most energy.
gas
Measures how tightly packed together a substance's atoms are and depends on if it will sink or float in water.
density
Energy in motion.
kinetic energy
Give one example of a solute.
sugar, salt
The center of the atom is known as the:
nucleus
As heat is taken away from atoms, they slow down and:
contract
Ability of a solute (salt, sugar, etc) to dissolve in a solvent (solution).
solubility
A change in matter that does not affect its chemical composition and keeps its identity.
physical change
Give one example of a solvent.
water, alcohol, oil
There are over 100 of these on the Periodic Table .
Elements
At atoms are heated, they gain energy and:
Expand
The temperatures that water freezes and boils (Celsius).
0*C (Freezing)
100*C (Boiling)
A change in matter that does change its chemical composition and identity.
