- Опубліковано 28 лис 2016
- This physics video tutorial explains the concept of thermal expansion such as the linear expansion of solids such as metals and the volume contraction of liquids like water. It discusses the relationship between the coefficient of linear expansion and the coefficient of volume expansion. It also provides an equation to find the expansion of area due to a change in temperature and not just length and volume. This video contains plenty of examples, formulas / equations, and practice problems.

Who else is watching in 2024 😂😂😂😂
Me😂
Me
Me
Me, its a big help in my studies.
why r u making noise in class
Everytime I hear his voice, I know he's about to save me... Thank you for sharing your knowledge and wisdom 🙏
Hehe
No be easy o
who else is watching this hours before thier exam? hahahaha
There many hour before exam but we choose read a book 1 hour before exam Why?
Me ;-;
So true
Me, i have an online f***** class
@@MUSICADISC143 me too and I'm not even ready😔
You saved me from the lecture that I didn't really understand... This man is the saviour fr
great video but new area was still in cm2 not m2. test in 3 hrs you are a life saver
i always watch your videos the night before my exams.
😺😺😺
I know, he is so cool!
There very well done aren't they! : )
Same thing I do here
This man just saved me 9 hours of continous learning, tysm.
At 9:35 it should be cm^2 not m^2 for the new area
Oh my same hahaha i watched it many times wondering why it became m^2
@@jessicasudio172 must be a mistake
glad this comment help, been dying to know why it became m
Very well really appreciative as a student I am saying that you made it very easy for us to understand it.
Youve been helping highschoolers for almost 5 years already, keep upppp
You explain this like my physics teacher but more in-depth. Thank you!
Hi, can I ask what's the formula in getting the original volume when dealing with liquids?
I slept when my lecturer was teaching...
Now, I had to be awake until midnight to prepare for the exam.....
you just simplified my life thank you
This man helped me in ochem II last year and now he's helping me with physic I
Like normal, you should honesty get the money that my prof is getting because you explain things sooo much better.
In the "area" question you calculated the differences of lenght and width separately and multiplied the new lenght and width to get the expanded area, and in the volume question you calculated only the difference in the volume. Which way is correct?
It does not give out the same answer unless you multiply the ◇V by 3 for volume (or multiply by 2 for area)
You are a life saver, my lecturer just made no sense today.
Thank you for saving my life everyday!!!
sir where can i found reaction on the alcohal phenol and ether
Am always happy simply because you act as if we are very closer hance boosting my knowledge
Great and Powerful OC Chem Tutor:
Please make a video on why in the hell the scales of Celsius and Kelvin are equal when it comes to coefficient of linear expension....
You are a real magic thank you man you've helped me alot
What if there is no space provided for the expansion and the concrete buckle up,how to calculate the height created by the buckling
sir please make more detail vedieo on thermal expansion
Why is there a -1 exponent on the first problem in its coefficient of linear expansion?
it's for 1/C.
Thank you for teaching,may God bless you.
Watching from Papua New Guinea🇵🇬
Thank you so much for creating such amazing videos in most needed topics, your effort is so greatly appreciated by us students.
if i had u as my lecturer, id actually be enjoying university, i probably wouldn't get straight A's, but i'd never fail, and understand everything im doing. i envy whoever had u as there lecturer. man usa has everything
@ 21:30 The Coefficient of volume expansion should be multiplied by 3 if im not mistaken
Why?
Excatly
thank you so much for this! it really helped me for my finals
Bruh u hv changed my life 10Q
When calculating change in area and change in volume we were taught to multiply the Coefficient values by 2 for area and 3 for volume....is this accurate?
Yes, it's gamma(volume) = 3(alpha) and in case of water, the coefficient is always 3alpha because length and breadth of water can even be the room in which it's put. Thus, it's gamma (which is equal to three times alpha)
This is so good Because it was interesting any one who can watch it
Im at the moment watching this while my professor is discussing this topic 😅
An iron ring 1.20 m diameter is to be put on a wooden cart wheel. The diameter of this wheel is 1.0 cm greater than that of the ring. The temperature of the ring that must be raised before it slips on the wooden wheel is (coefficient of linear expansion of iron is 12×10−6/oC)?
I need your help
ur video is great sir...plz can u tell me which software u r using...
We have a quiz at this moment, and i can't believe I'm just reviewing now
sir I thought you will change the temperature to the standard unit use to solve which is Kelvin
or am I lost
Thank you 🙏 I'm pretty sure these videos of urs helped out many graduated students, and they are still helping us even today although they were recorded years ago. Very appreciated 🙏🤍
2:15 hrs for exam this is a great help 👍
Why is that aswer different when you convert the temperature to Kelvin before starting to calculate
Shouldn't you be using the units intended for the formula?
Ur supposed to change each value into Kelvin then subtract them
how did you get the answer at 4:15 ?
a steel rail of length 20 m are laid at the temperature of 20°c an explanation gap 6mm is left between adjacent rail what resulting expansion gap in millimeter when the temperature of the rails is (a) 35°c (b) -5°c take the Coffeicent linear expansion as 12*10^-6
can i ask ,,why he didn't convert ml to m^3
my guy is an artist❤
thanks man tomorrow is an important test
What if you only heat up half the plate too
I'm going to thank you after I graduate 💖
I love you Soo much thank you, may God bless you ♥️
How is the original length 12cm???????? Helpp
You are amazing! 😭
You made physics interesting
What textbook do you use
Nice one ❤️
What if the coefficient of volume expansion is not given?
It wont happen😂xd
you helped a lot!
You the best!
sir you are using as alpha into initial length into change in temparature but not adding 1?in our school it is taught as new length[1+alpha into change in temparature]but here you are not adding 1 can i know the reason please
Y should u add 1
The new length will be the original length +change in length
why did not you take 1/C in example 2 like in example 1???
Thank you so much
How many of you just want to do the calculations but the pen is not nearby bcz you are watching it on your 🛌
Real
What if there's no given coefficient of linear expansion?
From 8cm * 12cm how can I know which one is Area? or w?
Yes and the width is the shorter one
In the first question isn't the change in temperature +75 because they said it was increased by 75 hence final temperature would be 95
it says (increased to) not (increased by)
9:28 is cm^2
hi do you do graph analysis for FS Physics, am currently getting 78% , i want to get around 85%, i would really use this types of videos for FS Physics
When will i multiply the beta by 3?
Volume Expansion is Cubical Expansitivity x Original Volume x Change in temperature.
To find cubical expansitivity, you multiply 3 by linear expansitivity, which is explained in this video.
my answer on the first problem was 0.0172m ? am I wrong ?
you're missing a 0
You're a godsend
Hey your final area is wrong. The unit should be in cm²
My saviour 👌
When he said "heres a new formula to help deal with-" i was like "no way!" Im gonna try do simple shit before the fancy shit
Anyways great vid, helped alot.
😂😂😂 same here I didn't even concentrate on the 2nd method. . it's complicated.
Quick question...is the temperature here is Atmospheric Temperature?
It's the temperature of the object which is typically atmospheric temperature unless you went out of your way to heat/cool the object.
@@joshuatanase3718 thank you...😊
menh this is my lecturer hahaha .Thanks much
Nice
thank youu
After this I'm going to the next video heat fusion and thermodynamics 😵
Phy god!!!! Tq sir
THANK YOU!!!!
Thank you
I understand lessons here at youtube than in face-to-face classes.
im lost why did you not convert it to meters? T_T
thanks 🙏🏼.
Volumetric expansion of the cyclinder
Thanks
is 1/k = 1/c
What is A???????
man you forgot to convert cm >> m so the answer for new area is wrong
For these types of problems, the units are irrelevant as long as all units remain consistent.
Shit comment
hi can we be a frinend ? this my wa +6289633050411i wanna learn with you

@@UltraFlamingRed 🤗
your square meter should suppose to be square centimeter not m^2
Yes you think what bro
at 21:31 forgot to multiply the coefficient by 3
But it says in the question volume coefficent so I don't think we have to
Anyone taking the sat physics in 4 days?
Who else is watching cause they didn't understand in class 🤣🤣🤣
Hahah it's me😂
I think you forgot that Alpha is in c^-1 instead of c, you suppose to multiply by the inverse of Alpha , 1/29 times 10^-6
Sir, c^-1 is equivalent to 1/c . c^-1 happened because you transferred c to the numerator, thus, giving it the negative exponent.
thanks bro but u better work on also linear expansion of liquids
How in the living hell can liquids become linear
Beni daniel you dumbass thermal expansion of liquid
96cm² is not equal to 96m²
my question too
