用水管隔空吸引鋁罐?│《科科學會了》把課本的「靜電(摩擦起電)」變有趣!-資源代表圖
靜電是什麼?靜電指的是電荷在物體表面不平衡分佈所引起的現象,當兩個物體互相摩擦時,電子會從一個物體轉移到另一個物體上,這種因為電子轉移而產生的電荷現象,就稱為靜電。靜電不會像電流一樣流動,它是暫時停留在物體表面的電荷,直到遇到導體或接地後才會釋放。以日常生活中的例子來說,當我們用塑膠梳子梳頭髮時,會發現頭髮變得容易吸在臉上,這是因為梳頭的過程中,電子從頭髮轉移到梳子上,使頭髮和梳子帶靜電,與臉產生吸附現象。

【自然系列-化學 | 化學反應02】(化學平衡)化學反應的神奇比例-下集-資源代表圖
古德柏格和瓦格兩位哥倆好,因為貝特羅的實驗開始反覆猜想與驗證所有可逆反應在溫度不變的情況下,反應到最後,原料跟產物會呈現特殊的比例。而這些固定比例則源自於物質的濃度和吸引力所達到的「反應平衡」。
