Physical Changes

QuestionAnswer
conservation of mass The particles in matter that are present before the physical change are the same as those present after the physical change. The particles are the same both before and after a physical change, the total mass before and after is also the sameEX: ice cube
dissolving things + melting Dissolving= when something evenly mixes together with another substance. Melting= when a solid becomes a liquid because heat was applied.
condensation is the process where gas turns into a liquid
sublimation when a solid turns directly into a gas without going through the liquid stage.
Deposition when a gas turns into a solid without going through the liquid stage.
Boiling when a liquid turns into a gas, because thermal energy was added
Freezing when a liquid turns into a solid, because thermal energy was removed.
Change of state of matter To change the state of matter the movement of the particles must change in order to change the movement of the particles, thermal energy must be added.
Movement + distance of particles in gas, liquid, solid After a solid has melted adding more thermal energy causes the particles to move even faster.
