It's actually nuts that your channel isn't bigger chief. Everything I've had to cover this semester, you've conveniently got a concise video in a consistent format for. Gonna be binging your videos over summer to get ready for next semester.
I'm in organic chem now and tutoring for general chem. YOU ARE A LIFESAVER CHAD! 24 The Lord bless thee, and keep thee: 25 The Lord make his face shine upon thee, and be gracious unto thee: 26 The Lord lift up his countenance upon thee, and give thee peace. Numbers 6:24-26
Amazing lesson! I have exam in 4 days and now i can easily do the problems so a win for me Also i wanted to know if you have any plans on making playlists for subjects like inorganic or analytical chemistry? Because i definitely wouldn't want to lose any of that
Great stuff Chad, you saved my life. Do you have scholarships/discounts for students who want to have access in your test bank and other resources? Thanks a lot.
Do you know by change if qsurrounding and qsystem are proportional? I have been seeing qsys= -qsurrounding. I was wondering if it's the same as saying -qsys = -qsurrounding. I was doing a problem asking to solve for the enthalpy change of the system given information of everything about the solution. I solved it and got a positive answer but switched it to negative since I was assuming they were proportional.
One thing I find confusing. I was taught that a rise from 5°C to 8°C is a rise by 3 K (Kelvin). Because °C is absolute. A temperature of 0°C doesn't mean there is no temperature at all. In fact 0°C is 273.15 K. And a rise of 3°C means a rise of 276.15K resulting in a very high temperature. Also in my Chem books the specific energy for heating matter is given in J/(kg•K) 🤯
The important difference here is to make the distinction between the temperature and a change in temperature (such as a temperature rise). 5°C ~ 278K and 8°C ~ 281K. These are temperatures and to convert from Celsius to Kelvin we have to add 273.15. But when you look at the change in temperature. A change from 5°C to 8°C is a change of 3°C. On the Kelvin scale this is a change from 278K to 281K which is a change of 3K. The mistake that is easy to make is to take a temperature change of 3°C and add 273 and wrongly state that it corresponds to a change of 278 on the Kelvin scale. A change of 3 on the Celsius scale will still be a change of 3 on the Kelvin scale. This is why the specific heat has the same value whether we use units of J/(kg•K) or J/(kg•°C) as specific heat is defined as the amount of energy to CHANGE the temperature of 1g of a substance by 1 degree. Note that this is for a temperature CHANGE of 1 degree which is why it doesn't matter whether we use Kelvin or Celsius as the span between degrees is the same on both scales. Hope this helps!

Thanks for saying so, D D - glad the channel is helping!
Chad, you are an incredible teacher. You explain things so well; I constantly have "eureka" moments when I watch your videos. Thank you so much.
You're welcome - and Thank You.

best calorimetry lesson i watched and it has been two days i was trying to learn this
Thank you - glad it helped out!
No words, Just wanna say THANK YOU. YOU ARE AN AMAZING TEACHER CHAD!
You're welcome and Thank You!
Amazing lesson!

Dude! You’re an amazing teacher. These videos are helping a TON in my engineering degree. How can I ever repay you?
Study hard and succeed - or give me your first born. Either one will do. :-P
Bud is getting me through AP Chem- thank you so much 🙏🏿
Glad the channel is helping you.
hey Chad, i am wondering about 8:41 answer , i think we have to multiply by mole not divide to it.
Great stuff Chad, you saved my life. Do you have scholarships/discounts for students who want to have access in your test bank and other resources? Thanks a lot.
Send me an email: chad@chadsprep.com 😊
Super super good video. Thanx!
You're welcome and Thank You.
Great video on the topic!
Thank you!
WOW this is really good
Thank You!
thank you so much for saving us
You're welcome.

Hi Chat! I couldn't find final exam (general chemistry) preps on your website, can you help me on that?
Thankss
They are in my premium General Chemistry Master Course after chapter 13 (for Gen Chem 1) and after chapter 21 (for Gen Chem 2). Hope this helps!
@ChadsPrep oh I see thank you for replying quickly :) and your work helps a lot, praying for your health 🫶
Awesome
Thank you.
Sir can you please share some worksheets if possible
we don't have worksheets for the channel but they are available on our courses on chadsprep.com
Nature wants to demonstrate calorimetry!! 😅
Indeed!
