[DSE Physics] Heat 熱

[@tomsmith1803]

唔洗睇都知高質！

[@nickyleung1397]

物理學家唔接受天眼通。

[@geoffreyyu5163]

點解我考完DSE都成日忍唔住返嚟睇嘅

[@MarcYam]

物理跟你一世，sad......

真！

勁 內容同教科書一樣 但係一聽就好似好容易 😂

[@raymondkwan2670]

演算法帶左我黎呢度

[@kahim0_0]

如果呢條片係我中三嘅時候有嘅話, 我有50+1%機會率揀physics

[@holeefuk8838]

👍就算我係考A-Level你啲片都係極之有幫助，感激萬分🙏🏻btw 等緊Gases😩

[@MarcYam]

A-Level??

[@kardensel98k]

多謝 我而家溫緊書

[@muijilee4874]

I watched this video before my GCSE mock exam, it is very useful😭😭😎

[@kobeho5679]

前日考final就係考physical chemistry, 今日就有片出😅 btw 已pass

[@ichigoxpsy]

好有趣，好想學physics，出多啲片，加油加油gchi gchi

[@yungcheng1699]

而家教物理要教埋歷史😂

[@MarcYam]

世界難撈呀而家......

[@Joe-it7of]

好正，睇完之後對物理好有興趣，可惜當初中學揀咗商科😂

[@MarcYam]

唔緊要啦，就算唔讀Physics 都可以學呀嘛。

今次真係好片啦

2:39 Why particle vibrate得越勁 會越熱 同要多啲位

[@MarcYam]

越熱即係啲particles震得越勁，之後我地講到kinetic theory equation就會講到。而要多啲位呢，呢個就都係靠計出黎，主要係計兩粒粒子既kinetic energy同average separation，我地會計同如果kinetic energy 越大，average separation就越大。

[@chashiu169]

Hello,Mr.Max Wong 過得好，期待你的E=Mc delta T and gas prssure

[@WTO1024]

Yeah 有新片🎉🎉😋

[@tko1225]

其實我有個想法 假設我將一堆音箱面向同一個方向，當我開啟這些音箱，佢哋嘅聲音嘅震動能唔能夠令物體溫度上升呢？

[@MarcYam]

會呀，如果個物體會吸收啲聲音，啲聲能會轉化成物體既內能。

[@siriusblox]

有科學發展史,正評! 感覺DSE phy chem 好少提到呢類nature of science

[@crosbybrownnewbold466]

好奇焦耳個實驗，感覺上熱嘅實驗流失得好勁，我上次上堂做度到水嘅比熱容係3萬幾😱

[@MarcYam]

其實我都未做過呢個實驗，但Joule好似都做得幾準呀。

[@一心-k8z]

3萬幾咩先？ U-1呀同學

[@yanyeep7720]

第二個好似!!!! 我愛marc sir :P

[@awpy2247]

Latent heat既能量會轉化物質形態咁係咪代表同一樣物質唔同形態所帶既能量都會唔同

[@MarcYam]

係呀，如果佢地質量一樣嘅話就會唔同呀喇。下集會詳細講

[@kprofessor7882]

Why particles average kinetic energy will increased 每一粒particle size are same? 唔係只係燒嘅個part D particles will vibrate stronger? why all particles will kE will increased

[@kprofessor7882]

Why not the particles KE will increased ?but is the Particles Average KE will increased? what are the different between that ?(i have watch the comment,there are someone questions like me but i don't get your answer about answer him)

[@MarcYam]

may this help you? kzbin.info/www/bejne/gIOvZ36Mjsl7sMk

終於有好physics 片啦...考完啦

正野

[@EdwardChan.999]

嘩原來背後有段咁有趣嘅歷史?!

[@hi9604]

那為什麼在四度以下的水會不遵守冷縮熱漲

[@MarcYam]

因為四度以下時，水分子行得慢，水分子會開始組合成較大水分子團，呢啲水分子團既結構會將撐開啲水分子，令密度下降，亦即係越凍越彭漲。

開黎做乜？

[@andrewchan7927]

簡單易明

[@andrewchan7927]

想問下宜家仲有冇熱質學？佢係咪已經被joule推翻咗？多謝

[@MarcYam]

已經推反咗，無人講熱質呀喇

[@cosmos11131101]

[@tszkeiii0.0]

係Heat呀哈利😭

[@ngsam817]

讀緊 engin 都睇返呢啲

[@gracekeung8530]

點解heat ↑average kinetic energy ↑唔係kinetic energy ↑

[@MarcYam]

因為kinetic energy同number of particle有關，如果number of particles增加，無heat，但total KE都會增加。 所以heat係增加average KE，而唔係KE。

[@changary7933]

咁即係分子運動理論可以用一句話嚟簡化: 當進行物質加熱嘅行為 熱會加速物質裏面嘅粒子運動 咁嘅話呢一句話可唔可以證明(或簡化)到分子運動理論？

[@MarcYam]

其實以前啲科學家擺明知呢兩個理論唔同，但搵唔到實驗方法證明邊個啱邊個錯咁解。

[@Kabigon-X]

點解你唔開營利, 應該夠資格😂🤔

遲啲有機會會開，如果我開嘅時候就會同大家解釋呀喇！

點解冰會畀水大😂 我同學係咁問我煩死我

[@tinakwok7600]

Hydrogen bond

[@MarcYam]

主要係因為冰有獨特既固體結構，呢個結構會撐開，令水分子間既空間增加。
