In this lesson, you will learn about the various temperature scales used in chemistry, physics, biology, and other sciences. We will focus on the Celsius, Kelvin, and Fahrenheit temperature scales. Celsius is calibrated so that zero degrees C is equal to the freezing point of water and 100 C is the boiling point of water. The Kelvin scale has the same temperature degree widths, but is shifted down so that 0 kelvin is defined to be when atomic motion ceases. We also will convert these scales into the Fahrenheit scale.

Thanks for sharing these lessons. A person can have an excellent teacher and still not get it. Sometimes we just need a different person teaching with a different way of explaining that makes sense in our brain. I love the internet.
30 years after school with a 6 year degree, only for temperature scale to make sense now. Excellent!😂
I learnt so much from this. Superbly presented and understandable as always. Thankyou sir for another great lesson.
Excellent video. The best explanation I have seen anywhere, including my old text books about Celsius Fahrenheit conversion.
I am an engineer by profession, but I am a science fan and it is difficult for me to find information or a guide on where I can study and your videos have helped me a lot. you have democratized knowledge. Greetings from Chile and thank you very much.
Great video, thank you!
This video is refreshing, it just reminds me about my days in school. I ❤ this video thank you so much
This video was very helpful for me.....Thank you!!!!
You are a really good teacher love your videos
Súper importante para química y física. Gracias profesor 😀😀👍👍👍🌟🌟🌟🌟🌟
Thank you, again
Congrats on 1M Subscribers!
Thank you so much!
Nice 👍
I'm so excited to continue these chemistry lessons & learning from you that I downloaded Vol. 1 & 2 from your website. Is there anyway to get downloaded lessons of these more current videos you've made in the blue shirt? Some of lessons are the same Volume, Unit, and Section number, but the content is different than what I've been learning here. (for instance Course 1 Unit 1 Sect 2 on here is "States of Matter", but in the website download Course 1 Unit 1 Sect 2 is "Units & Unit Conversions" ) Thanks!
Hey where is part2 I can't find it thank you:)
WHAT IS THE HIGHEST DEGREE GIRED BURN?
However, there are alternative methods for cooling an object aside from simply placing it in contact with a colder substance!
Very good video on this topic, but I was dealing with data overload at about 24-25 minutes into the video.
Interesting, in the light of all of that, how Kelvin (or anyone) was even able to come up with such a precise floating point value mapping (273.15) while at the same time not being able to reach the 0 point in practice. The 'temperature' of light/color, for that matter, is usually a coarse number like 6500K... Kind of leaves me pondering.
❤❤❤❤❤
What is twice as cold as zero c?
Ich habe gesucht. Брюки/broek ist Niederländisch. 3000 niederländische Wörter hat es im Russisch. Danke Peter der Große. 🇳🇱🇱🇺🇷🇺🇷🇺
22:04 I wish I heard that before I went to Italy lol
Where do we get 212 sir
What is the temperature of burning wood?
Hot - 800 degC
Dear, Mr. Jacob I'm so sorry for trolling you, you're a great teacher and deserve better 👍 hope you accept my apologies, could you forgive me
Fahrenheit scale tied, originally, tied to to body temp (at 100 degrees F)? . Not exactly came from nowhere.
What is with the 0.15 please.
Because the conversion to Kelvin is 273.15 not 273. Using 273 would introduce in accuracies into the conversion calculation.
You look younger and younger!!
Hi
الكلفن وحدة اساسية لقياس درجة الحرارة
عندما تكون درجة الحرارة صفر يتجمد الماء واذا كانت مئة يغلي الماء .
وهذه في كوكب الأرض ، إما اذا ذهبت إلى كوكب يدفعك إلى الاسفل اكثر سمكًا سوف تتغير .
اذا صعدت للجبال ليس هناك ضغط أقوى لذلك سيغلي الماء بسهولة - أي بدرجة حرارة منخفضة .
لذا ف درجة الغليان مئة والتجمد صفر هي الضغط الجوي الأرضي وتختلف مثلما قلت .
كيلسي كلفن = OK
يقول جيسون : عندما اقول صفر درجة مئوية فاعني صفر حركة - لا تتحرك - .
ويقول : ميكانيكا الكم هي أفضل ما لدينا لفهم حركة الذرات .
ويقول : يستحيل الوصول إلى صفر كلفن .
رسم مقياس درجة الحرارة :
_______________________
100° 0°
الكلفن =K
يقول جيسون : لا يوجد درجة حرارة بالسالب أدنى درجة حرارة هي صفر كلفن .
رسم مقياس درجة الحرارة :
___________________________
373.15 273.15
( كلفن ) ( كلفن )
درجة الانصهار درجة التجمد
الفرق بينهما 100 درجة .
K = C° + 273.15
Of scale مقياس فهرنهايت
عند درجة 32 فهرنهايت يتجمد الماء وعند 212 يغلي .
OF = 9/5 (C°)+32 ( قانون فهرنهايت )
يقول جيسون : فهرنهايت معقد لذلك لا يستخدم .
الفرق بين التجمد والغليان ( فهرنهايت ) يصل إلى 180° درجة .
١ كلفن = ١.٨ فهرنهايت ( اجتهاد )
كيف اتت درجة ١٨٠ ؟
180/100
تبسيط :
180÷2 على 100÷2
90/50
تبسيط :
90÷10 على 50÷10
9/5
لاحظ : قانون فهرنهايت .

You are the wisest. You should be the richest.
So why does the USA insist on using deg F for weather reports?
Who knows!
The last question I think 107.6 rounded up would be 108 not 110
It is 110.
@@ursulagwozdz1955 Hi could you or anyone else explain why it's 110 and not 108? I was confused on this part. Thank you in advance!
@@GoddessJihanMost likely just personal preference? 110 is a nice round number, but would pose some inaccuracies (around 1.5555°C). Sig figs would tell you where you *should* round your number.
Thanks for a great video 🤍.
Finally l understand this.
Where is 1-1-7 and rest?
Maybe in their website (purchase lesson or do a subscription (it's really cheap, well kind of)), or it was just not added to the playlist.
Why do they say 9/5ths? 9/5ths = 1.8 C*1.8+32 is easier to do in your head. Why do they teach 9/5ths?
9/5 is a very easy number to memorize.
Also, when you're converting from Fahrenheit to Celsius, you're going to use .5555555555++ which takes away so many sig figs, while 5/9 doesn't.
Memorizing the fraction form is just more efficient(?), to say the least.
Spare us.
Great vid, just can't wait for people to actually start defending fahrenheit 🤣
Fahrenheit is actually better for body temp.
Kelvin seems useless unless in the quantum world.
