Chapter 1 - Matter and Measurement: Part 1 of 3

In this video, I (Dr. Mike Christiansen from Utah State University) will begin my Semester 1 Undergraduate General Chemistry course. In this lecture I'll teach you about what chemistry is and why it's important. I'll also define numerous vocabulary words, such as matter, element, atom, molecule, compound, pure substance vs. mixture, gas, liquid, solid, homogenous vs. heterogeneous, solution, physical change vs. chemical change, and precision vs. accuracy. Furthermore, I will teach you how to classify a substance as being pure, mixture, homogeneous or heterogeneous. I'll teach you SI units and prefixes, and how to inter-convert between Celsius, Fahrenheit, and Kelvin scales.

Dude, you legit saved my life. You're awesome. I attend a community college in North Carolina, and my teacher moves so fast and a lot of us students struggle with the class. When I found you on youtube, I shared you with a lot of my classmates. You saved us! Thank you so much for your chapter videos! Im so glad I found you, because I was on the verge of dropping the class! ALL your videos are so helpful :) Thank you! From, all my classmates and myself :)

[LVBando]

I hate that questions are asked and then the answers aren't given.  Maybe at the end all the answers should be shown to see if we're correct.

Hello! I wanted to just directly message you but it doesn't seem possible on here so a comment is the best I can do. I just wanted to send you a huge thank you for your hard work and dedication to teaching. Without your videos and help I would not have passed my college chemistry class. It is so awesome of you to do these video lectures for your students and non students. I just feel like you should know that you are appreciated and there should be more teachers like you. You are teacher of the year in my book (exchange professor for teacher sorry). Also I love your cat memes and jokes. It lightens up the subject before a lecture and helps me to learn. Anyway, thank you again much appreciated and I'm sure il be viewing more of your lectures for college chemistry 2 and organic chemistry. THANK YOU!!! -struggling college student at CSU (Charleston Southern University).

I wish my chem teacher is you.. because my chem teacher is making us to memorize whole prefixes, temp formulas.. and whole vocabs from ch1 in her FIRST quiz. I like your style of teaching!

This is so helpful when i'm trying to prepare myself for my fall chem class

Mike, you're helping me prepare for the DAT man, thank you very much for these great video lectures. 

[lune-]

Thank you for this. You getting right to the point cuts down a significant portion of time compared to my online professor.

[chemistryunleashed]

You're very welcome. Thanks for the kind words. I should tell you that I'm not sure what you mean when you say that I should "post my youtube videos on the bottom of the video." Could you please explain further?

[EtheryteXz]

Im sorry, i was tired from all the studying. Now, what i mean is sometimes you post YouTube links on ur slides. I think if u can post those links in the description so we can check them out later on or go back to them.

[MyVoiceThyWord]

I don't understand my professor's heavy Indian accent. I go to class just for attendance. You have been of great help to me, Mike. Thank you very much

[MuskanSharma-jejk]

I was struggling to find a professor for chemistry and then your videos showed up. Kudos to you!!
Thanks very much for helping students like me to get a better hang of the subject.
Great work!!!
Gonna watch them all :D

[mafodimichael]

I'm so looking forward to doing chemistry this year since you are using the same text book as us. I'm a student of Metallurgical Engineering in the university of the Witwatersrand in South Africa and I love your work. Thanks a lot!!!  

[chemistryunleashed]

Oh, gotcha. I can do that. I just added them in the description for you.

[cathiel]

My profesor just plays clash of clans and other games in his ipad thanks for being a good profesor :)

[areejalghamdi]

I Am from Saudi Arabia thank you very much, you best teacher explain chemistry 👍
