Mo5-L3b: How Does Matter Change From One State to Another?

SUMMARY
Key Concept How Does Matter Change From One State to
How Does Matter Change From Another?
One State to Another?
Describe the changes in thermal energy as water When thermal energy is added to a liquid,
goes from a solid to a liquid. vaporization can occur.

When enough thermal energy is removed from
matter, a change of state can occur.

Conservation of Mass and Energy
When matter changes state, matter and energy are
always conserved.
