Particle theory and states
According to the Particle Theory of Matter, all matter is made up of these
Particles
The change of state when a liquid turns into a gas.
Evaporation
A pure substance that cannot be broken down into simpler substances.
Element
The subatomic particle that carries a positive (+) charge.
Proton
The name given to the starting substances written on the left side of a word equation
Reactants
The state of matter where particles are tightly packed and only vibrate in fixed positions.
Solid
The change of state when a gas cools down and becomes a liquid.
Condensation
A substance made from different elements that are chemically bonded together.
Compound
The subatomic particle that carries a negative (-) charge.
Electron
The final substances formed at the end of a chemical reaction.
Products
The state of matter where particles are far apart and move completely freely.
Gas
The process of a solid changing directly into a gas without melting first.
Sublimation
Two or more substances combined together but NOT chemically joined.
Mixture
The subatomic particle that has a neutral or zero (0) charge.
Neutron
The process where particles spread out from a high concentration to a low concentration.
Diffusion
This is what particles do to each other according to the fourth statement of the Particle Theory.
Attract
The process of a gas transforming directly into a solid.
Deposition
Along with soil and air, this everyday beach mixture consists of salt and what other substance?
Sand
Melting, dissolving, and freezing are all examples of this general type of change
Physical
In an experiment, this is the specific variable that you choose to change.
Independent
When matter is heated, this is what happens to the overall speed of the particles.
Faster
When water is placed in a refrigerator, this is what the particles lose.
Energy
Water (H2O) is a compound made of oxygen and which other element?
If Potassium has a mass number of 40 and 19 protons, it has this many neutrons.
21
In an experiment, this is the specific variable that you measure.
