The Particle Theory Flashcards
Matter
Something that has mass.
Made from particle in which can be arranged into 3 groups
Particles
A very small portion of matter
Atom
A shallow component having the chemical protecter
Solid
When the particles are close together by the strong force of attraction
Liquid
When particles are still touching but can move around. It changes shape and is hard to squash.
Gas
When the particles are far are part with air in between. It can b squash easily and change shape.
State of matter
The matter are arranged in different ways to make 3 states in which are solid, liquid and gas.
Boiling point
When melting solid, the particles vibrate. The hotter it gets the less fern the particles are and eventually it can turn into liquid.
Freezing point
The particles in a liquid slow down as they get colder. Closer the particles get the better it turns into a solid
Evaporation
When the particles in liquid move so much that they start breaking away from each other and move individually. Then some of the liquid turn into gas.
Condensation
When the particles slow down as thermal energy. When they come together they form liquid.
Freezing
When the liquid or gas particles slow down and the colder it gets the tighter the particles stick together.
Melting
When the particles in a solid vibrate till they start moving. The hotter it gets the more until it forms into a liquid
Solution
The mixture of solute breaks and dissolves in solvent
Solvent
The liquid that dissolves in/into
