QUÍMICA
CLASS 101
0:10 - 0:18

Hello guys, I'm professor Rufini and I'll be here in our classes,
you can see aulalivre.net
0:19 - 0:22

Together with you on the Chemistry Class
0:23 - 0:31

In our meet today, we'll work on a proposal that is
usual in every test on Brazil
0:32 - 0:36

It aproaches the matter of material systems
0:37 - 0:43

And clearly in the first moment, we should tell what
a system is
0:44 - 0:46

Easy to understand
0:47 - 0:56

System is any limited portion of material of the Universe
that we will gather for analysis
0:57 - 1:05

And from the moment I make the analysis of that porcion
I am able to say to you, what material is this
1:06 - 1:10

What characterists, what properties this material shows
1:11 - 1:13

That, for us, is a system
1:14 - 1:19

Just that everyone, a limited portion of material that we get
to study
