....那個阿 你要不要先去查什麼叫做Van der Waals force
什麼叫做London dispersion force
不要只會看中文WIKI 中文WIKI一堆搞笑錯誤已經很久很久
要不然就是資料有夠少到可憐 並且會誤導人

最後 有關鍋子加熱那邊懶得打太多字了
也請你去查一下熱傳導的差異...表面溫度跟稍微離開一點點的溫度可以差多少...


那個啊..., 請指正上述中文wiki中對於Van der Waals force 的敘述當中的錯誤?
https://en.wikipedia.org/wiki/Van_der_Waals_force
Being the weakest of the weak chemical forces, with a strength between 0.4 and 4 kJ/mol,
they may still support an integral structural load when multitudes of such interactions are present.
The force results from a transient shift in electron density. Specifically,
the electron density may temporarily shift more greatly to one side of the nucleus.
This generates a transient charge to which a nearby atom can be either attracted or repelled.
When the interatomic distance of two atoms is greater than 0.6 nm the force is not strong enough to be observed.
In the same vein, when the interatomic distance is below 0.4 nm the force becomes repulsive.


如果Van der Waals force真的足以黏住食材, 那麼在冷鍋中打入一顆生雞但也應該要黏住了.
畢竟壁虎爬玻璃不限定滾燙的玻璃嘛...
https://en.wikipedia.org/wiki/Van_der_Waals_force
The ability of geckos – which can hang on a glass surface using only one toe
– to climb on sheer surfaces has been for many years mainly attributed to
the van der Waals forces between these surfaces and the spatulae,
or microscopic projections, which cover the hair-like setae found on their footpads.

表面溫度跟稍微離開一點點的溫度差?
我沒有否認過萊頓弗羅斯特效應啊.
但是熱鍋到萊頓弗羅斯特效應程度後, 東西丟下去就會持續萊頓弗羅斯特效應?
不知道有誰能手濕濕的"按住"燒紅的鐵鍋不受傷?
東西丟下去就能靠萊頓弗羅斯特效應不沾嗎?
更誇張一點說, 萊頓弗羅斯特效應的力量足以撐起食材的重量使食材懸空?
不要鬧了吧...
