Particles And Atomic Structures
States of Matter
There is a weak force of attraction between liquid particles. They are free to mave around and past each other but tend to stick close together
Liquids have a definite volume but don't have definite shape and the particles are constantly moving in a random motion
The hotter the liquid gets, the faster the particles move
There are strong forces of attraction in which holds them close together in fixed position to form a lattice arrangement
Particles don't move from their position and they keep a definite shape and volume
The particles vibrate in their position
the hotter the particles become, the more they vibrate
No definite shape or volume and will always fill any container
they move constantly with random motion
either expand when heated or pressure increases
very Weak forces of attraction so they are free to move and are spread out.
the particles in gas travel in straight lines
Diffusion is the gradual movement of particles from a high concentration to a low concentration
Potassium manganate will diffuse in water. The color will slowly spread out into the liquid
Solvent: a solvent is a substance that dissolves a solute
Solute: the component in the solution dissolved in the solvent
Solution: Mixture composed of two or more things
Saturated solution: A solution that has the maximum concentration of a solute dissolved in a solvent.
Molecule: group of two or more atoms held together by chemical bonds.
Atom: a unit of matter that has the properties of an element. It is made up of a nucleus and the electron shells. The nucleus is composed of protons and neutrons.
Elements and Compounds
Compounds: is a substance made of two or more molecules
Element: a substance whose atoms all have the same number of protons
Solubility is the amount of grams that can dissolve in a certain amount of a substance
If a low amount of a solute dissolve in a solvent it has a low solubility
If high amount of a solute dissolves in a solvent it has a high solubility
There are many factors that affect solubility but on of them is temperature
