Calorimetry: Using q=mΔTc to find Temperature + Example

Hot Iron Bar + Cold Water = Final Temperature?
Use the formula mΔTc = -mΔTc to show that heat gained = heat lost and solve for whatever "x" is. In this case, it's the final temperature.

HI - larious.

[@Nick-li8ol]

ty this 7min video helped me more than my 2hour long class U________U

[@The_Chosen_Heretic]

+nickOP I agree!

[@purplepanda7993]

agree

[@saulmunn3710]

same

[@peachypear8765]

for real 😭

[@chemistNATE]

Absolutely. You can carry units throughout the whole thing if you like. I find some students get lost when there are units floating around the linear equation though.

[@Palomino0813]

Once more, you've taken an equation that my textbook hopelessly overcomplicated and made it simple, and once more you have my thanks.

[@Im-me504]

dude you saved my life because my chemistry book was confusing the shit out of me with something so simple as this math equations you used.

[@oskarkristinsson6517]

thank you i've been up for to long trying to find a good explanation you're a life saver.

[@juandelacruzv3722]

Who else has finals tomorrow....? :)

[@jennahaor0244]

today >.

[@truedarkness4052]

Yep

[@shellyschwartz9908]

SAME

[@turtleboy440]

Me

[@eduardomenchaca1916]

Me tomorrow 😂

[@victorialipps7061]

Because of you I will do great on my chem test! Thanks so much!!

[@MizJustice]

The way this video just saved my life!! Thank you chemistNate!!!

[@christinamccarthy7659]

Cant thank you enough for doing this example. My prof made this question WAY more difficult than it needed to be and you simplified it making it painless and easy to solve. THANK YOU!!

[@clairetellkamp6253]

Bro, i love you. You're the only one I could find who answered this.

[@ZeddsWorld]

thank you! this was way more helpful than my physics teachers lecture

[@ABWBackyardWrestling]

This helped so much you have no idea. Thank you so much!

[@Texman4268]

FANTASTIC. what a great explanation and thanks for breaking down the steps. Explained it a LOT better than my Physics guide did, that's for sure!!! Thanks again!!!

[@dayneornelas296]

bless youuuuuuu!!! your "you need to learn something" comment made my night of chemheartache lol

[@koalasandfries]

this is awesome thank you Nate!! A way more simplified version to what I learned.

[@stephens2663]

You're the man... I finally understand this!!! Thank you for making this!

[@Emily-xs8um]

OMG! Thank you so much! You helped me so much. I have been struggling with this concept for days!!!!!

[@alonator09]

OMG, made sooo simple! thank you so so much! bless you

[@whitneyxox4u]

you have no idea how much this just helped me!!! thank you tremendously !!!!

[@sliderulelover]

Very well presented. Kudos to your teaching technique. You also anticipated student's questions as you went along. Well done!

[@jamesgibbons8855]

Very very helpful!!! Thank you so much for taking the time to do this!

[@connorgoff3740]

This video was the only one that solved my question...thanks!

[@lindsaykearney5089]

Haha I never realized how weird it is until now, but my chemistry teacher writes the formula as q=mc🔺t and she pronounces it like "q equals mcat" 😂

[@guardado56143]

Same with me, I find it easier to remember

[@arasa8896]

Lindsay Kearney onlar ne bilsin :D

[@sasamusic27]

haha wow that’s so funny man 😂

[@justynsc96]

9 equals mcat is a good mnemonic if you are studying for the MCAT exam, which requires you to know this equation ;)

[@MK_BABE]

lol

[@FHO72]

I love your videos. It's always so simple and straight forward. Thanks for making it easy for us struggling chemistry students. PS. MAKE MORE VIDEOS

[@azizsaleh7508]

Thanks alot man, been around this equation for an hour ...

[@aaronrapp4120]

BOOM! Nicely done best of luck

[@HanSoloxcs]

This just made a lot click for me. Thank you ChemistNate!

[@mrswhiteschemistry4934]

Thanks for posting this. I found it helpful and will use it with my students.

[@Erikola18]

Thanks man you're a lifesaver!

[@migbasketballer]

Thank you so much for posting this video! I have a test on this in two days and this helped me so much!!!! Thank you.

[@natpat7683]

This was so helpful . I am forever grateful.

[@iriscantrell]

Thanks so much! That was really helpful!

[@normaeunicechavarria6191]

Thank you !!! I used this for a two part equation were the initial for the second part was the final for from my first part !!! Work out perfectly!!

[@bodhi6481]

Thank you! SO much easier than I thought

[@kaden56]

finally figured it out now that's it's 12:30 am thanks to your video! Thank you!

[@seanbyrnes6789]

This was extremely helpful!! Thank you very much!!

[@FranciscoGarcia-jy9rn]

thank you so much, I am reviewing for a final exam and this is helping me out.

[@LuisMartinez-rg5tr]

Thanks a ton. This was pretty helpful!

[@macristinagalvez]

You’re awesome!!!! Please make more videos!

[@4Yiger]

Thank you so much! I was so confused with my chem homework until I watched your video.

[@chelseaswan316]

Thank you so much!!!! This was so helpful to me!

[@renrenx3328]

You made me love algebra! Thank you so much

[@sicilianotoronto]

Thank you! I tried this tonight but the Chem text was making the math so difficult to solve! You make it much easier!

[@AndreaMercado13]

You are an amazing teacher!

[@katierobey-bhamani4435]

idk why but this hella made me laugh. but thanks I needed a memory refresher on this before my test tomorrow

[@chr7688]

Thank you so much for this video. I've just spent 3 hours trying to solve a problem that you made simple in 6 minutes. Completely different than all the other examples out there but finally, logic I can understand!

[@The_Chosen_Heretic]

+ch r I've been spending roughly 6 hours on mine!

[@shindo567]

omg i have a test on this tomorrow! youre amazing haha, i know ill do better now

[@ladashimartin5954]

Very helpful. Thank you so much!!

[@rosemarydelgrosso8685]

I just wanted to say thank you so much for this video. My teacher gave the worst clues on how to solve a problem like this one so I am truly grateful to you.

[@jackpodlasek9183]

i fucking love u @chemistNATE

[@johnmcnash9174]

Thank you so much this video was a life saver

[@dasherman5150]

Good video. Thanks. I'd suggest dividing both sides of the linear equation by -4.6 as a second step though. It makes the numbers more manageable with only 'x-80' remaining on the right side.

[@samfitzgerald7353]

Extremely helpful 🙏

[@alexperez9180]

thanks for uploading, really helped alot

[@Madpainter88]

SAVED MY LIFE! i have been trying to figure this out for ages and my text book is shit!. Sir, you earned yourself a sub! ily

[@julesg6602]

10/10 Would solve again

[@chattywattypatty]

Thank you so much! So helpful

[@corylatham3835]

Thank you! You explained this perfectly! :)

[@maddisonreeve2896]

How do you know what should be - and + for the initial plugging in of information? Is water endothermic?? Not quite sure what is going on with this part.

[@ChrisBranleh]

Great! this helped drastically in my chemistry II class.

[@DhritiPMurthy]

Really helpful!!!
:D
chemistNATE

[@williebangs1600]

Good job 👏 this video really helps

[@christinamccarthy7659]

Do you have other examples of these types of Calorimetry problems? If so, can you direct me to the link? I would greatly appreciate viewing a few more of these.

[@imranwahabi3351]

helped me soo much bro thanks

[@Manishh95]

love the videos, you'd be a great teacher sir

[@sscbasil9690]

Well said!! Thank you

[@slg4567]

Literally just saved my life!!! yessss Thank youu

[@SonicParkour6]

very helpful, thank you!

[@anjalimathur6818]

amazingly explained

[@7641955]

Thank you for making

[@nickkoryukin4949]

At 2:12-2:15 did you mean 70mL or what you wrote??

[@yordanibenitez4753]

Amazing! Thanks !

[@varshiniramesh2941]

THANKS A TON! This helped a lot. :)

[@ellieb4306]

Why isn't the Ms 80g? I thought you're supposed to add both masses?

[@jrzrd411]

Wouldnt the units cancel? So you would have joules?

[@BurritoNations]

Thank you, sir!!!

[@MsAndreasd]

Thank you so much!

[@ameehasa5504]

Sir I have question I want to mixed one gallon water at 10 degree how much can I add hot water at 40 degree to get water at 30 degree ?

[@j0kokoh]

How would you solve an more complex problem involving 3 masses and 3 specific heat capacities asking for mass? e.g ice dropped in a glass of water

[@scottsibley561]

Did you ever find out how to complete these? I'd appreciate some resources on how these are done.

[@melvinvasquez8518]

Thanks! CHEM 121 final tomorrow. This looks way harder in my textbook when you are casually glancing through; lol.

[@CrayEditz]

is the x in the answer the final temperature to the iron to the water?

[@mrswhiteschemistry4934]

I'm just starting a youtube channel to help my students. I love your explanation. What do I tell them about dropping the units during the workup? Do they actually cancel out as it progresses?

[@DC-bk3oh]

Thank you thank you thank you thank you!

[@luisambriz4673]

if you combined like terms why is there only one x in the end?

[@SquiggleWyrm]

How would you do this if there were three components? But two of them have the same change in temp.
EX. 80 degree Copper dropped into 30 degree Celsius water held in 30 degree Celsius cup

[@bruhmoment3834]

Thank you so much.

[@insane204]

thank you so much for making this video and making it so simple ive been trying to learn this the whole day and with your video i can finally understand it thx a lot

[@insane204]

I don't know why when I search ur guild It tells me somethings wrong I'll keep trying

[@lBankedlXboxGT]

lower case L uppercase B anked lowercase L Space uppercase YT

[@ignacioaguilarluna3697]

How can u find mass with this formula.....I really need it plz help

[@PanggaKoko]

Thank you much for helping people like me :)

[@nascar12141]

Does it matter which - sign you put, either on iron or water? for q=-q... Either way result is the same, but is there any actual assignment of the negative sign?

[@danielivashin2177]

Thank You!
