What is matter
A physical substance
What is plasma
a state of matter made up of charged particles that have an undefined volume and shape
what is deposition

What is it called when thermal energy flows between particles
Heat
during sublimation is energy released or absorbed
absorbed
what does pascals principal state
A change in pressure to one part of a contained fluid is transferred without change to the entire fluid
What is the major difference between a colloid and a suspension
The particles in a colloid are smaller and don’t naturally settle out of a mixture over time.
