I’m so angry how my teacher decided to skip these important parts of the lesson so thank you
That is why grades depend on the teachers we get :/
Teachers are SHIT
Really
@@nikhilkhatri9556 Yes really
Broo sameeeeeeee
You are a legend. Not many have the ability to explain as well as you.
This method for solving calorimetry is so easy and understandable… Thank you
You could also expand ΔT into (Tf - Ti), and expand m into (Tf - Ti). Then you can move both mTi’s to one side of the equation and both mTf’s to the other side, factor out Tf from mTf + mTf to get Tf(m + m) and solve for Tf.
Finally I’ve been looking forever. At least I know how to do one question. The other ones are ridiculous like trying to figure out the amount of heat in a reaction when you’re given moles, volume in mL, the change in temperature, specific heat and the density of the solution. I don’t know how to find the mass with all that. Like I have a suspicion that I have to use D=m/v but none of this stuff is in the class’ PowerPoint or even in the class textbook’s sample problems so I have to resort to UA-cam. 😢 I know I’m on a tangent but I’m frustrated that I can’t actually get the help I need with all of us being in quarantine. Like I just went over problems with my teacher a while ago but this stuff he is quizzing us on isn’t what he is teaching us during our class sessions. But anyway thanks for helping me with one problem.
Now we are suffering this kind of learning style, we are now in a modular type even though that we are already college. Streesful because we don't understand the module, examples are not indicated to the module so how can we asnwer those activity given. Hayyystttt.
Thats why I really thankful because I learned a lot for you. Thank you so much..
Professor Organic Chemistry Tutor, thank you for a solid analysis and explanation of How to breakdown and solve Final Temperature Calorimetry Practice Problems in AP/General Chemistry. Once again the practice problems/examples really shows the importance of Calorimetry Problems in Modern Chemistry. This is an error free video/lecture on UA-cam TV with the Organic Chemistry Tutor.
How would you handle a problem where there were two different pieces of metals with different specific heat capacities?
Socal Fritos I have the same problem!
did you ever find out? I need to know too :')
You will have to add those two metals together. It will be:
mc∆T of metal 1 + mc∆T of metal 2 = whatever is gaining energy from metal.
It's been one year though so I assume you know how to solve this already.

@@frazebean5117 Thank you sir, helping the next generation
Bro thankkkkk you , I am doing my N3 engineering science and I struggled with this sum for an hour until I came accross this amazing video
You are a life saver! This has helped me immensely
Thank you so much. These videos are literally saving my chem grade
You should win some international teaching award.
my teacher used the book the molecules of life and made us do these questions. I had no idea how to and the bumass book doesn't even provide answer key for students. Thank you so much I learned everything from u!
the book made this soo much harder. You rock
amazing result i tank you sir! i will take confidant into examination subject of engineering mathematics because you! god bless
You are a god amongst men. I was looking for a problem like number three to be explained for much longer than I care to admit before finding this gem. Thanks a bunch
it's like magic when he's solving :D
Your channel is bombastic to prepare for iit jee advance I request you can you upload lectures of inorganic chemistry
Omg my teacher didn’t teach me this important part !!!
Damn searching for your channel & found it Wanna give you million thanks✨
Tankew so much.. This is very helpful I'm sure I gonna pass my exam next week
this is exactly what I needed! thank you so much
Thanks so much for your easy solution! I was confused for 24h.....Thanks a lot
OMG. I LOVE YOU! YOU MAKE MY LIFE EASIER. 😭♥️
Bro just got me extra credit points on a graded problem set. TY
I would like to add how i solve these problems because my professor taught it like this
I'm gonna use problem 2 for an example
(40g)(0.89j/g c)(170 c)+(50g)(4.184j/g c)(20 c )/ (40g)(0.89j/g c)+(50g)(4.184j/gc) = 41.8 C
bro istg ur the best teacher i literally love you bro
PLEASE ANSWER ME, WHAT IF IT IS 0.11 cal/g-°c
ARE YOU GOING TO PUT A NEGATIVE SIGN LIKE -0.11 WHEN SOLVING THE PROBLEM?? I REALLY NEED HELP PLEASE ASAP
Thanks a lot.God bless you with many more years to live ,you are saving the courses of poor people like me.u are simply the best.i like the way you teach and the way you come up with the questions,u leave no question that is for exam purpose.All of your questions are for exam purpose.
once again man, THANK YOU!
What do we do if the specific heat is like.. not the same? Like two different substances?
number 2 covers that I think
I love you organic chemistry tutor
thank u soooo much im really really happy to see this video today before my final exam 💗💗💗💗 but i hope if u can raise your voice a little, this was perfect thank you again 💗😘
I know this is weird but I love your style so much and you are cute
@@leahk6380 yeah this is weird
doing a question in the same style as question 3 but all the energy on one side =0
couldnt do it until now
thanks
Thank you so much. Our teacher tell us to do numericals ourself. It's really difficult to solve it on my own. This video helped a lot. Thanks a lot💖.
Shouldn't you subtract the final temperature from the initial in the case of the higher temperature, since no matter what the final temperature will be less than that?
No, delta t can be negative
you are a lifesaver
this was very helpful thank you!
Thank you!! I appreciate you!!!
His voice 🧑🏻🦱 his knowledge 👨🏻⚕️🕵🏻♂️👨🏻🚀
what would you do for something similar to the last question. say if the pot with the water has a higher temperature than the lead.
would both the q of pot and q of water be released to lead? or would it be just the one with the higher heat capacity
Why is it that a random guy on youtube's video can explain a concept so much more precisely than a teacher's video?
Thank you so much!
Thanks so much! Helped a lot!
Thank you
Thank you!
So why are we able to add Tf of aluminum to Tf of water? IE: 8:15
Great video, How can we contribute to your channel?
how can we know that the tempertaure could not be any lower than 25'c
,, is it because the one will be absorbing and one will be receiving, so,, it cannot be any lower between that interval
To avoid unnecessary confusion, for heat loss equation always make specific heat capacity as a negative value...energy removed
When did eminem start narrating chemistry videos?
Thank you sir👍
Thanks man
how do i solve it when it's the initial temperature that's being asked?
What is the case if its surrounding air around a pipe and i calculated the heat transfer rate as k watt ?
how can I get the final Temp. !?
sir why is nt the first question's answer is like this?
50g *c*(T-25) = 100g*c*(90-T)
then the answer will be T = 68.3 degree Celsius
you have taken T-90 why sir?
The question asks for the final temperature of the mixture, hence the final temperature of each substance is unknown.
why isnt the negative distributed to all of the numbers on the left side?
negative sign is only given the substance that releases heat which is the hotter one because it undergoes exothermic rxn
it is
I'm so confused??? Every video I go to has two elements/compounds mixing with their own temperature when mine has two things mixing with only one having a temperature??!?!??!
My teacher explained it so wrong
My guy how will you get rid of the rest if the unit?
at 3:46 how did he know to write the equation like that? I'm not really following how he determined which one had to be negative
either of them can
If 1 g of steam at 100°C steam is mixed with 1 g of ice at 0°C, then resultant temperature of the mixture is?
I can't get the answer for the life of me.. Can someone help?
Amazing
lol I got the same answer and I just did:
90 + 90 + 25 = 205
205/3 = 68.33333333333333333333333333333333333333333
I WAS WONDERING WHY THE TEMPERATE FINAL IS NOT EQUAL TO THE MEAN
(i guess what im saying)³ is i.. I F-ing Love Yaaaaaaaa 💝
I love you bro
I have no fucking clue what I'm doing, the principal switched my class from biology to chemistry and they have already started the 2nd lesson, so I have no dang idea what to do.
الله يشرح صدرك للإسلام
My teacher didn't even teach us and just make us do the prob 🤡🤡
Curse NSW preliminary textbook
"temmiture" pff I mean thanks for the vid :)
can you do a face reveal
😂
Your a lifesaver 🥲
Can you pleas make a video on C.P and S.P? E.g. S.P=$64 L=25% C.P=? I need help asap please
