a pure substance is 1 substance, and has only one kind of atom or molecule.also, only made up of 1 type of matter.
a mixture is made up of many substances, and has 2 or more types of matter.It can also be separated.But, it might not be easy to separate.
*in a boring voice says* have a great day,come again*sighs*
All particles of a pure substance are the same. Every water particle, called a molecule, has 2 hydrogen atoms and 1 oxygen atom.
All particles of a mixture are not the same. Salt water solution has some water molecules and some salt that are mixed together.
don't freakin know! im trieing to find out too!
Pure substances are composed of only one element, having no added impurities. Mixtures, however, are made of many different substances that are placed together
A mixture contain more compounds each wih his type of particles. In a pure substance particles are the same.
Neither, try again.
how will you use the particle theory to explain why a saturated solution at 30 degreecelsius can become dilute at 70degree Celsius
Diffusion is evidence for particle models because it causes diffusions
The thermal energy of a particle is directly proportional to its thermodynamic temperature (ie. its temperature in Kelvin).

Particle theory of light can explain Photoelectric Effect,Compton effect,Pair production.... wave theory of light can explain interference,refraction...
The smallest particle of a substance that retains the chemical and physical properties of the substance and is composed of two or more atoms; a group of like or different atoms held together by chemical forces.
atom is the smallest particle of matter
atom is the smallest particle of matter
You can use the particle theory to help explain what happens when solutes dissolve. The particle theory states that there are spaces between all particles. This means that, in a sample of water, there are many water particles, but also many empty spaces. When you look at sugar. The sugar dissolves, the sugar particles separate and mix with the water particles.

There is speculation among particle physicists that say these forces are the result of photons that are exchanged between particles.
