The answers are: 1) there are different ways through which the heat is transferred from heat source to another substance, the first one is conduction that takes place in solids where the molecule gets heated and further vibrate and transfer the heat to other molecule, the process continues till it reaches incognition temperature.the second one is convection that takes place in fluids. the molecules first close to heat source get heated causing them to expand (( *---*) : molecular space between fluids usually) ( *-----*: space when they get heated) and move upward and to fill the space the colder molecules come and get heated too until the temperature of all the molecules are same( also maybe because the hot molecules are light and the cold molecules are dense so when the molecules get heated they move to the top and the cold molecules come in the bottom to fill the space) can you tell me which of the theory about convection in liquid is correct ? In air when the surface is heated, the space between molecules increases and they move upward and to fill the space the cold molecules of air come to fill the space and continue (related to land breeze and sea breeze)Next is radiation that doesn't require a medium to travel , for ex :when the heat rays from the sun come to surface and even from the heat source the heat are examples of radiation. ( I have not understood radiation fully so can you explain ehich medium is being talked about the molecule or the beaker). I don't know whether the answer is correct or wrong as i am new to this topic but if i have made any mistake, do correct it.
Hello, I don't include the answers because these videos are used as graded assignments for students. I do not want to provide the answers in the description or the comments, as it undermines the validity of the assessment.
Answers are found throughout the video. I cannot simply write the answers or include them all in one place because that would allow cheaters to get an unfair advantage.
Nice video thank you so much😊😊
Thanks for this wonderful class❤❤
nice video thank you so much
thanks i had to practice for my exam😊
Thank you for the time .
Thank you for watching
Thank you
Thank you
👍
Thanks

Thank
D, B, C, A, B
god bles you
Thanks i was studyng for a test 😂
You're welcome.
So was I
Same
Same 😢
Mee too😂😂 😂😂😂😂😂😂❤😅
Can you tell us the answer?😊 please I really need it for a test.😢😊

Me too
Wow
Where is answer

I promise I did not cheat
May you
D,A,C,A,B
#2 and #4 cannot both have the same answer. Only one can be conduction.
Thank
