What are protons?
Solid directly to gas
The random motion, or vibration, of atoms in matter
What is thermal energy?
The amount of space occupied by any three-dimensional solid
What is volume
The neutral particles found in the nucleus of an atom
What are neutrons?
The phase in which atoms lose their electrons

The tool used to measure density
What is a hydrometer?
The region around the nucleus
What is the electron cloud?
Being absorbed into the substance during the change
What is endothermic?
Holds molecules and atoms together

The measurements used to calculate volume
What is mass divided by density
The # of protons in an atom
What is the atomic number?
