What is Matter? By: Chris

Matter can be split up into two sections which is pure substance and mixture

Matter is a physical substance in general, as distinct from mind and spirit that which occupies space and possesses rest mass, especially as distinct from energy.

Matter can be broken

'not that kind of breaking nora' 'awww why not that breaking '

' because nora this is about matter ' 'ok' 'like i was saying before i was rudely interrupt matter can be broken down into two categories: pure substances and mixtures. Pure substances are further broken down into elements and compounds. Mixtures are physically combined structures that can be separated into their original components. A chemical substance is composed of one type of atom or molecule.'

'uhh what ' 'nora focus ' 'sorry ' 'pure substances is a compound or a single element. An element is a pure substance that cannot be separated into simpler substances by chemical or physical means. There are about 117 elements, but carbon, hydrogen, nitrogen and oxygen are only a few that make up the largest portion of Earth. do you want to say anything nora' 'uhh no I mean yes maybe?' 'good'

'NORA pay attention'

'Sorry Ren' 'this would be going faster if you would focus' 'what do pure substances look like ren?' 'well nora they look like this'

'got it ren so there is what they look like'

'yes' 'soooo what's next' 'oh yeah I have not talked about mixtures I will make it easy for you nora it is like your pancakes' 'oh how' 'well it takes mixtures of ingredients to make pancakes are you following a long.' 'yes' 'ok lets move on to elements ' 'okay'

'elements are each of more than one hundred substances that cannot be chemically interconverted or broken down into simpler substances and are primary constituents of matter. Each element is distinguished by its atomic number, i.e., the number of protons in the nuclei of its atoms.'

'compound is a thing that is composed of two or more separate elements; a mixture any questions nora.' 'no ren' 'good moving on'

'And this is a compound Nora'

'Homogeneous consisting of parts all of the same kind.'

heterogeneous is of or denoting a process involving substances in different phases (solid, liquid, or gaseous)

'Candy gimme' 'no nora '

'next is solution and solution is a liquid mixture in which the minor component (the solute) is uniformly distributed within the major component

'and this is solution'

'And next is suspension a suspension is a heterogeneous mixture containing solid particles that are sufficiently large for sedimentation. Usually they must be larger than one micrometer.'

'and moving on to our last one'

'can I do this one Ren' 'uhh I guess' 'ok colloid is a mixture in which one substance of microscopically dispersed insoluble particles is suspended throughout another substance.

'I guess it works Nora'
